S3·E4 Nerd for a Day

Jesse tells Stephanie that she must apologize for going along with her classmates in teasing Walter, a kid who wears eyeglasses, but the apology makes Walter think Stephanie loves him, and when Stephanie's friends come over to the house and see Stephanie talking to Walter, they make Stephanie a target for teasing, until Stephanie turns the tables on them, and shows them how it feels to be teased. Meanwhile, at school, D.J. has been assigned to follow and observe a person for a day, then write an essay about that person. D.J. chooses Michelle to be the subject for the essay, and on ""Wake Up, San Francisco"", Joey fills in for Becky as Danny's co-host while Becky is out of town.
