Continuity mistake: When Drake and Josh are trying to pull the phone from the base, the phone gets thrown across the room into the fish tank and breaks. Then about two scenes later the phone and base are back on the table and fixed up.
The Peruvian Puff Pepper - S3-E2
Character mistake: Drake says he hasn't been in Megan's room since he was five, but he brings Grammy's bags up there in the episode "Grammy".
Dune Buggy - S1-E2
Visible crew/equipment: When Drake and Josh first get into the Dune Buggy, there is a person under it.
Continuity mistake: In the beginning after Drake asks Josh, "what guitar do you think would look best." He opens up the cabinet and paint squirts his face. At first it only squirts his forehead, but when it switches views you can see his whole face is covered.
Revealing mistake: In the scene where Jerry cuts the little girl's pigtail off, it is obvious she is wearing a wig.
Continuity mistake: When Drake dumps out the snacks on the table with Josh's puzzle on it, he knocks the puzzle box off the table, but when Drake says "The mean man is gone" the puzzle box is back on the table.
Continuity mistake: During the scene in the science classroom, the teacher draws a circle on the chalkboard and refers to it as a picture of the human eye. In following shots, this picture constantly changes from having other parts like irises and pupils to just being a blank circle.
Continuity mistake: Near the end, when Josh whacks the thug with the bat, the thug falls to the floor and his hat flies across the floor. In the next shot the hat has moved closer to him.
The Peruvian Puff Pepper - S3-E2
Revealing mistake: In the scene where Megan puts the stuff in the salsa and stirs it with the spoon, she takes it out and it is clean, then Josh stirs it again and the spoon comes out clean again.
Factual error: In the scene after they won the football game, the football players and cheerleaders all come running into the locker room. At no time would girls be allowed in a boy's locker room.
Factual error: The game the team plays was supposed to be the game to decide if they are going to make the playoffs. Usually those games are near the end of the season. If it was, they wouldn't have tryouts after the season is almost over. (They would have tryouts before the season started).
Continuity mistake: In "Football", when Josh is trying to act cool near the beginning, it does a shot of the wall he is going to lean against, and there is a small shot of the bottom of the "WET PAINT" sign, and it is pink. Then, when the camera looks full-on at the sign, it is black and white.
Continuity mistake: After Zeek gets injured and Josh decides to play himself, when he runs out screaming and comes back in, you can see a poster in the hallway but the words aren't clear so its hard to see. When the game is over after he scored the touchdown there is a totally different poster in the hallway.
Continuity mistake: When Drake is at the radio station getting ready to play his song, he is holding a 12-string guitar but when he races home to play for Wendy, he has the same guitar but it is now a 6-string.
Continuity mistake: When Megan loads the tomatoes into her machine, she only loads three tomatoes. When she attempts to shoot at Josh, she shoots all three tomatoes, but when her mom clicks the button again it shoots another tomato.
Continuity mistake: Walter drops the burger on the table, but it falls off the plate. In the next shot, the burger is back on the plate. (00:03:20)
Continuity mistake: When Megan is passing out the pop quizzes, she reaches back with her right hand to hand them to the kid seated behind her. But in the next shot, showing the kid she is handing them to, her left hand is holding the quizzes. (00:13:10)
Continuity mistake: In the episode "Honor Council" when Mindy is at the stands, Josh refers to Mrs. Hayfer as "Mrs. Alice Hayfer." But in this episode, when Drake is watching the DVD of Mrs. Hayfer on "Search for the Stars", her name appears as "Linda Hayfer."
Revealing mistake: When Josh lets go of the gutter and falls on Walter's boss, if you look closely and watch as Josh falls on top of him, it's a dummy in Josh's clothes. The dummy is much lighter than Josh was at the time and its ankle twists backward.
Little Diva - S2-E7
Factual error: After Josh brings Ashley her refrigerator (that was apparently originally meant to be a sandwich), and it falls on top of him, Josh tells Drake it's "cold in the wrong places", while a boxed refrigerator couldn't possibly be cold, as it wouldn't be connected to electricity and therefore its heat pump wouldn't be working.
Chosen answer: It's just a screaming fan that knows everything about Drake.
