Continuity mistake: When Fry is queueing for the booth, he opens the piece of paper, showing the picture and writing. Just before he steps in to the booth, it's changed colour and gone blank, then in the next shot it's back as before. (00:07:45)
Visible crew/equipment: When Dewey yells for Lois because the bow was put on the present, if you look to the left of Lois, you will see a crewmember kneeling down, handing Lois the Red Dress, who is holding a bucket of water. He quickly gets out of the camera's view. [This is on the DVD of the first season. Someone said on the audio commentary that after catching it, they deliberately left it in to see if anyone would spot it. It's still a mistake, but that's why it's there.]
Daddy's Little Beauty - S4-E12
Continuity mistake: When Fred is trying to work out what kind of talent Pebbles has, she has her bathing suit on. When Pebbles is seen crawling onto the stage when it's her turn, she has her regular clothes on, and when Pebbles is on the stage with Dino, she has her bathing suit on again.
Continuity mistake: After Candy and the stunt man quit the movie, Mr. Maxwell says he has to withdraw his job offer to the gang as it's too dangerous. As the gang is shown, Scooby is sitting in front of Shaggy and Fred. It cuts to a close up of him as he gets excited about this, and suddenly Fred and Shaggy have vanished. (00:06:10)
Other mistake: After the turkeys start attacking in "The Running of the Turkeys", Mr. Fishoder and his brother start running. In that clip a Turkey pops out the side of a guy's head. Look in the mid lower right side. Looks like a design error. Pretty big error, no slow down needed to see it. (00:05:20)
Star-Crossed Lovers and Other Strangers - S1-E16
Visible crew/equipment: When Rory asks Lorelai to call Emily to get her out of Friday night dinner so she can celebrate her and Dean's 3-month anniversary, a boom mic drops into the shot as Lorelai stands to get the phone. (00:07:05)
Continuity mistake: The gang investigates the trail of limestone to a manhole in the middle of the street, with nothing around it. But when Daphne is putting on her "Wallowing galoshes" boots, somehow a small brick wall just materializes in the middle of the street for her to sit on - and then vanishes a couple shots later. Not just the fact that it appears and vanishes between shots, but that there is a random brick wall in the middle of the road. (00:05:10)

Beware Greeks Bearing Gifts - S1-E12
Visible crew/equipment: As the people of Troy are about to be attacked by the warriors in the horse, the camera pans up to the side of the wall where Deiphobus is talking with another soldier. You can see a crew member crouching down behind them wearing a white and grey shirt. (00:30:35)
