Brian Kagan is a character who appears in season three of Full House, and is one of Stephanie's friends who lives in San Francisco. He is also apparently friends with Laurie and Harry Takayama. Brian's first appearance is in "Misadventures in Babysitting". D.J. Tanner is hired to babysit Brian while his parents are away. However, despite D.J.'s honesty towards him and her wanting to be friends with him, Brian causes trouble and chooses to make a mess in the house, as well as tossing a vase into the air and then hoping it hits the floor and smashes so he can pin the blame on D.J. (who actually catches the vase before it can hit the floor and smash); even going so far as to steal her purse in the process and bribe her into giving up half her pay to be his friend. But the tables turn on Brian
