<P> ^ Note 1: Scott Weinger, John Brotherton, Ashley Liao and Adam Hagenbuch are credited after the opening credits and only for the episodes in which they appear . </P> <P> ^ Note 2: Scott Weinger is credited as a Special Guest Star in the sixth episode of season two but as starring in all of his other appearances . </P> <P> Jesse Katsopolis (portrayed by John Stamos; the character's last name in season one was Cochran, but was changed reportedly due to John Stamos wanting his character to better reflect his Greek heritage) is Danny's brother - in - law, Pam's younger brother, husband of Rebecca Donaldson and father of twin sons Nicky and Alex . Born Hermes Katsopolis (as revealed in the season five episode "The Legend of Ranger Joe"), he was named after his great - grandfather, who in turn is named after the Greek god of swiftness . However, he did not like his birth name, as other kids teased him for it; so when he was in kindergarten, he begged his parents to have his name changed to Jesse, thinking that one had to have a "cool name" to be in the in - crowd . As an adult, he was more confident with his true name, telling the girls about the Greek god of speed, and how his great - grandfather saved a village from a volcano, but still goes by Jesse . </P> <P> In contrast with Danny, Jesse is portrayed as being irresponsible most of the time, but occasionally serves as a responsible adult when a responsible adult is needed (such as when he discovers Stephanie's classmate is a child abuse victim in the season 6 episode "Silence is Not Golden"). Jesse is revealed as a high school dropout in season six's "Educating Jesse", though in an earlier plot (in season four's "One Last Kiss") about a high school reunion, he mentions not wearing his cap to his graduation because he did not want to mess up his hair . </P>
