Rent-a-Pop - S2-E7
Plot hole: After the meeting with Zack's "fake Dad", Mr. Belding informs Zack he wrote a letter to see the Dad again... However when the "real" Dad sees the fake "Belding" (whom the Dad didn't know was fake), the Dad never questioned about the "seeing him AGAIN" letter when this real Dad never met Belding before.

Plot hole: When Barney's telling Andy about the poem written on the bank wall, Barney blames Opie and doesn't mention anything about Opie using chalk, but when Opie walks in Andy tells him, "Barney says there's a poem written on the wall of the bank, and that you were standin' along beside it with a piece of chalk in your hand," and then in a few moments Opie explains that some big kids pushed the chalk into his hands. So it's impossible for Andy to have known that chalk was used to write the poem, and not a marker, a pen, or a pencil.
Normal Boy/Birth of a Salesman - S1-E3
Plot hole: Throughout the show, many characters state that Jimmy was responsible for the meteor almost destroying Retroville in the episode "Normal Boy", however, how would anyone even know that? The meteor was put on course after being hit by some kitchen objects shot into space by Jimmy's orange juice machine. Neither Jimmy nor his parents or anyone saw the objects go into space, much less witness them causing the meteor head straight to earth, especially since the meteor wasn't detected until the next day.
Worlds Collide: Part 3 - S3-E6
Plot hole: In their previous encounters with the Triceratons, the Turtles had to learn the hard way that the Triceratons breathe not oxygen but a combination of nitrogen and sulfur, which is detrimental to most Earth lifeforms, and thus had to wear special rebreathers. When the Turtles, Splinter, April and Casey enter Zanramon's throne room along with Traximus, none of them wear any breathing equipment to protect themselves from the hostile atmosphere.
And So We Commence (1) - S8-E24
Plot hole: When Theo is complaining that his father is inviting too many people to his graduation, he says "I saw him in the backyard 5 minutes ago hosing down the beach chairs", but this couldn't have been possible because in fact, Cliff was upstairs right before that scene, and then went straight to the living room, so there's no possible way that Cliff could have been in the yard at the time Theo had said he was.

Plot hole: When Lizzie and Gordo are sitting at lunch, Gordo says that he doesn't like broccoli (referring to the pile on his plate) and that he tries to avoid it. However it is established in many scenes that Lizzie's school has a self serve cafeteria, so why does he have broccoli? (00:56:45)
The Kidney Stays in the Picture - S7-E16
Plot hole: It is explicitly stated in this episode that Hayley was conceived in 1996. While normal for shows without character aging to change birth years to benefit the plot, this move was premature. Hayley's permanent age is stated as 18, and this episode implies that in 2012 she would be much younger than this. The whole plot centres around her being legally able to drink in a bar, so this is a pretty big mistake.
Scenes from a Barbecue - S3-E24
Plot hole: All the kids and Arnie are about to play a basketball game. Darlene and Chuck Jr. battle in Rock, Paper, Scissors to see who picks first.

Plot hole: In the first series, Bomber mentions 'City's my team', referring to Bristol City, and dislikes the other Bristol based football club (Rovers). If this is the case, why is he wearing the distictive blue-and-white quartered shirt of Bristol Rovers in series 4? I know that people change allegiances, but it's very unlikely.
Drew and the Motorcycle - S6-E19
Plot hole: In this episode, Drew acts like he is "Kyle", an alter ego he creates once he gets a motorcycle and starts to date the insurance agent who stops by. During the scene where the insurance agent, Drew, Lewis, and Oswald are in the kitchen, Lewis grabs the pan to hit the insurance agent over the head and Drew fights with him, Lewis responds "Drew" and the scene goes on normally. Lewis calls Drew Drew, not Kyle, as he is supposed to be called. If the insurance agent had heard him be called Drew, she would have known it was Drew, and not Kyle, all along.
