Dave Coulier and Bob Saget first met at a comedy show in 1979. When Dave first moved out to LA, he lived on Bob's couch.

Bob Saget's known for his raunchy stand-up material and would sometimes get in trouble for the language and jokes he made on set, especially because he would forget kids were around.

Mary-Kate and Ashley used to call all the cast members by their character names off set so they wouldn't mess up during filming.

The Olsen twins almost quit after season one. Their mother was worried about them having a "normal" childhood, so producers forked over a major salary raise to keep them.

The show was originally about three comics living together titled House of Comics, but since family sitcoms were trending at the time, they decided to change the concept of the show, and thus Full House was born.

There was supposed to be a 9th season. However, due to network changes, most of the cast started announcing they weren't coming back. They decided to end the show versus losing their main cast members.

The creators saw Jodie Sweetin in Valerie and created the role of Stephanie Tanner with her in mind for the part.

Lori Loughlin, aka Becky Donaldson, was only supposed to appear in six episodes, but the audience liked her so much, the producers made her a series regular.

Mary-Kate and Ashley Olsen landed the role of Michelle because they were the only two babies who didn't cry during the auditions.

In the beginning of the show the producers didn't want the audience to know that Michelle was played by twins, so they credited the girls as Mary-Kate Ashley Olsen.

Bob Saget wasn't the original Danny Tanner. There is an unaired pilot starring John Posey as Danny.

The Tanner home is located at 1709 Broderick Street in San Francisco.

There is only one episode that was actually taped in San Francisco.

Jesse Frederick, who is responsible for the Full House theme song, also created the theme songs for Family Matters, Step by Step and Perfect Strangers.

John Stamos changed his character's name from Uncle Adam to Uncle Jesse before the first episode aired!
