 This is about the biggest mistake of Full House. First, in episode 77, Jesse is on a school reunion, and he talks about his graduation, so he GRADUATED. Then, when he has to pick a
    best man for his wedding, and Danny tells him it's against tradition to have 2 best men, Jesse sais that he doesn't care about tradition and didn't even wear a hat on his graduation.
    Later, in episode 126, when DJ has to do a project to prevent students to drop school, Jesse sais he was a drop out, which means he did NOT GRADUATE.
 In season 1, episode 15, A pox in our house Joey says he can never get chicken pox and then gets it but then in season 4, episode 75, Viva Las Joey, at then end when he and his
    father start talking his father says that Joey got his sense of humour from him and Joey says he doesn't think so. Then his dad says sure you did, remember when you had the
    chicken pox and i watched cartoons with you all day. I thought that he had never had chicken pox and only got them when Stephanie got them.
 The upstairs of the Tanner house sometimes has a bathroom next to Stephanie and Michelle's room and sometimes that is Danny's room. They use the door for a bedroom in one
    episode, for example when Stephanie and DJ make a whole in the wall, and use it as a bathroom, when Jesse and Joey are changing Michelle in the first season.
 There seems to be some misunderstanding in the Tanner address. We all know it's 1882 Gerard Street, but in the series, there are some alternatives:
    * In one episode, when Stephanie is really nervous, talking to a boy she likes, she says in a hurried voice that she lives at 1883 Gerrard Street. 
    * In the episode where Joey finds an old girlfriend, he is talking to her on the phone and tells her to "Come on over. I'm at 1882 Gerrard." 
    * But what is even more strange is that their front porch does not agree with either of those answers. In the 8th season episode 'DJ's Choice', the number next to the door clearly
    shows '1892'.

    her that there was more to him than just long hair, rock&roll and a Harley. Though Jesse didn't have long hair when Becky met him. Besides, Becky's mother didn't meet Jesse until
    the day before the wedding, so how could she complain......?
 In the first episode with Rusty, when the doorbell rings, Danny says he'll answer it. But he opens the back door, not the front door, where the bell is.

 Whenever any of the cast is walking upstairs, they are supposed to be shown coming up from the livingroom stairway. In the episode where the dog Minnie shows up, Stephanie
    walks up the stairs in the kitchen and ends up on the stairway that is supposed to be the livingroom stairway. Its the same thing with Jesse when he comes home from touring with
    his band all summer in the fifth season opener.

 In episode #45, "Tanner Island", D.J says that Mickey Mouse is make-believe. Stephanie says that he can not be make-believe because they shook his hand when they were at Disney

    Tanners lived on Full house, the Giblers never moved once.

 In the first season, when cousin Steve comes by, Jesse knows how to play basketball, but in the later seasons he can't play at all.
 In the episode "No more Mr. Dumb Guy" Jesse talked both with Joey and Becky about the fact, that he left school, but later in the episode "Educating Jesse" nobody knows about that.
 In the episode "Jingle Hell" we see DJ, wearing the violet belt from karate. Later in the episode "A Little Romance" Becky makes her reckon up her good qualities. As one of them she
    calls, that she has got the green belt in karate. But green is much more earlier than violet. And in the episode "Working Mothers" DJ just gets her green belt.
 In episode 131 "Designing Mothers" Vicky's mother redecorates the room of Stephanie and Michelle. Then in episode 134 "Birthday Blues" they are suddenly in their old room, because
