Character mistake: In the courtroom, Cindy and Bobby are repeating their fight over spilling ice cream and Cindy says "You spilled ice cream on my dress" but at the start of the episode when coming home from the store, Cindy is wearing pants, not a dress.
Continuity mistake: In the courtroom, as Carol is giving the judge her side of the story, she's looking in the direction of Mr. Duggan the whole time while saying "otherwise he wouldn't have hit me." Then the camera changes angles and instantly Carol is turning from facing the judge back towards Mr. Duggan.
Continuity mistake: At the start of the episode there's a wide shot of the house exterior as the Brady's station wagon is pulling into their driveway, and the wagon has wooden side paneling, but in the next closeup the paneling is gone. Plus the fact that the rear-end damage doesn't exist in the first wide shot, which is the point of this episode.
Today, I Am a Freshman - S4-E4
Other mistake: In one of the final scenes, Peter ignites his volcano on the patio in front of Marcia and the members of the Boosters Club. As the volcano goes haywire, Marcia and the Boosters are shrieking as the lava/mud covers them head to toe. Somehow Peter, who is much closer to the volcano, is unscathed by the eruption and remains free of any dirt.
Fright Night - S4-E6
Continuity mistake: When Jan, Marcia, and Cindy search the boys' room Cindy finds the slide projector under Greg's bed, and when Marcia holds up the transparency slide with the "ghost" image, the close-up of the slide presents two problems. First, the "ghost" is horizontal in the wide shots, but is vertical in the close-ups, and second, the fingers holding the slide in the close-up do not belong to Marcia.
Fright Night - S4-E6
Continuity mistake: Mr. Brady places the bust on the half-wall behind the couch. When Alice swings her purse at it, it shatters immediately, but when the lights are turned on, it looks like all of the pieces are in the middle of the floor between the couch and chair.
Fright Night - S4-E6
Plot hole: After the girls get their revenge on the boys in the attic, they explain the mysterious "I must have air" voice from the trunk as it's revealed to be from a tape recorder. Marcia mentions a set up the girls had where they played the tape recording (from their bedroom) when they were ready. This is impossible as the recorder was in the attic trunk and the play button would have had to be manually pushed down by an actual person to activate.
Continuity mistake: The CLOSED sign behind Sam in the butcher shop keeps alternating between being tilted to the left and tilted to the right. (00:14:45)
Visible crew/equipment: After Bobby tells Alice that he can't pass Jan the potato chips because he's "not here", when Greg walks in and Bobby tells Alice that Greg's "not here either" we can see the tape mark on the floor behind Jan.
Continuity mistake: While the kids are practising the potato sack race as Jan watches from the sidelines, when Marcia steps into her sack and hops away there's a large color image on the front of the sack, but when she reaches Peter, then turns and heads back the image has vanished - it's not on either side, then it reappears when she's back with Bobby. Additionally, when Cindy hops in the sack that Greg was in, the sack is ripped at the bottom and Cindy's feet are on the grass, but when Cindy reaches Peter the bottom of her sack is perfectly intact.
Career Fever - S4-E9
Plot hole: Peter thinks he has a fatal disease. The parents realise two pages stuck together and he went from page 95 to 98 mistakenly. However, Mike first read about the actual fatal disease info on page 97, and then Carol read about what Peter actually had on page 96 (poison ivy). If Peter read only 95 and 98, there would be no way of Peter to know his disease was fatal since that was printed on page 97.
Goodbye, Alice, Hello - S4-E10
Continuity mistake: Greg is wearing dark dress shoes when he comes in to the yard playing football with Peter. When they enter the kitchen, Greg is wearing white sneakers, and when Greg enters the living room, he is wearing the dark dress shoes again. (00:01:15)
Continuity mistake: Jennifer writes her phone number on Greg's right hand with the first number starting at his thumb, but when Greg looks at his hand to read the phone number, the phone number was written with the first number near his fingers and the last number written by his thumb. (00:02:50)
Audio problem: In the scene where Mike comes home and Carol has ruined his golf club, you hear a door open and close, with a latch/doorknob. She hears it and knows he is home. But he comes in the back door, which was a sliding (glass) door. (00:20:00)
Continuity mistake: When Marcia is cheering in the backyard, her locket tucks itself into her shirt when she finishes.
Continuity mistake: When Greg comes home after Jennifer gives him her number, Greg is seen entering the house in the living room. Then a few seconds later he is seen entering the other side of the kitchen.
Everyone Can't Be George Washington - S4-E12
Continuity mistake: When Jan's in the backyard checking on the cloud and moon set decorations being painted by Marcia and Cindy, there's less "dark and gloomy" paint actually painted on the cloud after Cindy stands up with the smiley moon. (00:06:20)
Continuity mistake: The amount of garbage in the abandoned house - especially in front of the fireplace - increases from one shot to the next. (00:16:20)
Other mistake: When the frog jumps on the pizza (during Greg and Rachel's date), the gooey cheese mess resembles more superimposed tacky glue than actual melted cheese.
Character mistake: When the Brady kids are practicing for the talent show, instead of saying, "Come on, Pete," Marcia says, "Come on Chris," which is the actor playing Peter's real name (Christopher Knight). (00:14:30)
Answer: I think I remember that episode - but, more importantly, my mother always told me (and my siblings) to stop jumping/ stomping, running in the kitchen, and opening the oven door when a cake was baking... because these could make the cake fall. I believed my mother... and I, as a child, also caused a few "fallen cakes" because I didn't quite always listen (right away, anyway). I'm sure Alice's fallen cake episode was exaggerated, but cakes really CAN fall from stomps and opening the oven door too soon. Usually, it has something to do with the baking powder and how the air bubbles change during the baking process. Doing something that might cause the oven and cake inside to move/shake can suddenly change the air bubbles inside the cake and cause a collapse. I don't know all factors that have to occur for a cake to fall (collapse in the middle), but I've seen fallen cakes during my adulthood and... well... caused at least a few myself. Regarding Alice's cake falling each time one of the Brady kids stomped upstairs, I'm not sure if a series of falls could occur. IF it is possible, I think there would have to be way too much baking powder in the batter or some other inaccurate combination of ingredients that alter the chemical process during baking.
