John Stamos reprised his role as Full House heartthrob Jesse Katsopolis on Friday for Late Night With Jimmy Fallon. Jesse and the Rippers, Katsopolis' band, performed four of their greatest hits - including the Full House theme song.
Have mercy! The performance concluded with a reunion featuring former co-star Lori Loughlin, who played Rebecca Donaldson-Katsopolis on the series.
Stamos currently stars on USA's Necessary Roughness.
