Here are the mistakes for the show Good Luck Charlie on Disney.
In the episode, "Bad Luck Teddy, PJ is getting his hair cut by the woman, but, if you notice, the sign that says, "Barber Shop", the sign faces the right way from the inside, so, on the outside, it would be backwards.
In the episode, "Duncan vs. Duncan", Teddy says, "Party", in a way so that the actress portraying Charlie can say it correct moments later.
In the episode, "Study Date" at the end of Teddy's video, Gabe is on the stairs, but, when it cuts to show the whole room, Gabe is suddenly on the couch. He didn't have enough time to get there.
