Don't you wish that the casts of old TV shows would come together to produce one more episode?Jimmy Fallon was able to make that happen when he had the cast of Full House reunite and perform a sketch together for his talk show.

Dave Coulier, Bob Saget, and John Stamos appeared on 'Late Night with Jimmy Fallon' for a sketch that could have easily been part of the original show. Jimmy Fallon, who was sitting in a replica set of Michelle's old bedroom, expressed concern over leaving The Late Night Show. Danny, Uncle Jesse, and Uncle Joey rushed in to console him.

Of course, this sketch would not be complete without any running jokes from the show. Watch the video below, and it will leave you saying 'HAVE MERCY!'
