Teaser: Joey, Becky, and the twins shake, rattle, and roll. Main Synopsis: When Danny goes out on a date with Gia's mother Claire, Gia and Stephanie start fantasizing about how cool it would be if they became stepsisters. Michelle doesn't think that's a cool idea at all, because Stephanie has been ignoring Michelle in favor of Gia, making Michelle feel left out in the cold. Meanwhile, Jesse's new band, "Hot Daddy And The Monkey Puppets", is scheduled to perform at the Smash Club, but after an argument with D.J., Viper is too depressed to play his guitar, so Jesse helps Viper and D.J. work things out.
After his wife is killed in a car accident, news anchorman Danny Tanner recruits his brother-in-law Jesse Katsopolis (a rock musician) and best friend Joey Gladstone (who works as a stand-up comedian) to help raise his three young daughters: D.J., Stephanie, and Michelle, in his San Francisco home. Over time, the three men as well as the children bond and become closer to one another.
Danny is reassigned from his duties as sports anchor by his television station to become co-host of a local morning television show, Wake Up, San Francisco, and is teamed up with Nebraska native Rebecca Donaldson.
