Full House - Season 2 Episode 15 Pal Joey

A little over a year and a half ago, when Jesse and Joey moved into the house, Jesse and Joey didn't exactly get along with each other very well at the beginning, but since then, they have become good friends, and it's making Danny feel left out because lately, Joey has been taking Danny for granted. When Danny confronts Joey, they remember the day they became friends back in the 5th grade on February 23, 1968, when they protected each other from a bully named Sheldon. When Danny and Joey head to the school where this happened 21 years ago, they literally unearth the pledge they signed, which was a pledge to always be friends. Joey apologizes for taking their friendship for granted, and then he and Danny call Jesse to the school so Jesse can add his name to the pledge. Meanwhile, Stephanie's friend Harry has a crush on D.J., leading Stephanie to accuse D.J. of stealing her friend.
