Jimmy Fallon will be leaving the Late Night show to run The Tonight Show soon next month. Last night, Fallon opened the show featuring a reunion of the Full House characters Bob Saget, John Stamos, and Dave Coulier. Fallon was in his pajamas in bed when he told the three of them that he was nervous about hosting The Tonight Show. This skit is an excellent parody of Full House because Saget, Stamos, and Coulier reprise their roles of Danny Tanner, Uncle Joey, and Uncle Jesse. They even use their signature catch phrases from the show and sing the Teddy Bear song.
