Stephanie Plays the Field - S4-E22
Other mistake: It looks like she has earring holes. Didn't she get her ears pierced later on in the series?
Other mistake: When Rob dials the radio station, he dials the phone number and then looks it up in the phone book. He covers for himself, and then has a hard time keeping a straight face afterwards.
Suggested correction: The part is Rob checking to see if he had the right number.
Other mistake: The tenant board member tells George that Mr. Eldrige in apartment 8C has decided he wants the new apartment. However, the new apartment in question has a 3-digit number - 808 I believe. This indicates that the building would not have single digit numbers and letters (Such as 5E, 8C, etc.) as part of its numbering system.
Other mistake: In the episode "It's About Time!", near the end of the episode after they get back, when the camera zooms in on Phineas and Isabella, Isabella's face is gone - only her eyes remain, but after the camera zooms out her face is back.
Grandpa vs. Sexual Inadequacy - S6-E10
Other mistake: Look closely when the clerk scans the books. Ueberroth is a brown book, and Al Gore's book is green. The book that sends the message to Al Gore is the Ueberroth book.
Boating Buddies/The Krabby Kronicle - S6-E9

Other mistake: The 4 band members, all their equipment, months worth of food supplies, I am assuming medical supplies, change of clothes and other sundry items all magically fit into a small two seat helicopter.
Introduction to Finality - S3-E22
Other mistake: During Leonard's "Let's Potato Chips" YouTube video during the ending credits, you can see the video reaches the end of the load/play bar (watch the circle), yet the video continues for several seconds. Once the circle reaches the end of the load/play bar, the video is over and won't continue.
Episode Six - S1-E6
Other mistake: After the wedding when everyone is outside, Smithy says he has forgotten the maps that gave directions to the reception. Bryan says he can use the sat nav in his Picasso and tells everyone to follow him. But he was driven to the church in the Bentley with Stacey, so his car wouldn't have been there.
Andy and Helen Get Married - S1-E1
Other mistake: Sam Jones' son, Mike, tells Aunt Bee that the farmhouse has been in their family for 150 years. While showing Aunt Bee a photo album, he points to a photo and says, "That's my great-great-grandfather who started this farm." Pointing to a woman in the same photo, Mike says, "That's my great-grandmother. She lives in Philadelphia." It is very unlikely that the daughter of a man who had started a farm 150 years earlier would still be alive. Assuming the man started the farm when he was in his 20s, he would have had to father a child when he was in his 70s and she would now have to be in her 100s.
Other mistake: In the opening of this episode the screen reads "3:50pm On a Wednesday." When Gino (Frank's Brother) is reading the letters meant for Shadynasty, he says "Meet me at the airport, Friday, at 5:00, Terminal C." The gang and Gina then go along to the airport that very afternoon - a Wednesday - to try and meet Shadynasty and get her and Frank back together. And of course she is there, despite it being a Wednesday, not a Friday.
Other mistake: When Sportacus jumps out of his blimp, his crystal is missing.
The Karate Kid Returns - S6-E14
Other mistake: When Tim and Wilson are talking about The Beach Boys song lyrics, Wilson says he wrote a book called 'The Psycho-Physiological Indices of Amorous Connections Among Termites of the Southwest' that sold four copies. In an earlier episode called Wilson's Girlfriend, the woman Wilson dates also says she wrote the same book with the same number of copies sold.
Welcome to the Family Part 2 - S2-E25
Other mistake: Throughout this episode, Max is captured by villains and is about to be bitten by a vat of hermit crabs. It's pretty obvious that between every scene of Max, instead of the platform lowering, it's just getting higher. Clearly, Max should've got to the hermit crabs about halfway through the episode.
Other mistake: At the beginning of the episode, when the mermaid goes underwater, she holds her breath.
Other mistake: Archie goes out to the outside front porch to paint it. At the end of every show, the house they show doesn't have an outside front porch.
