Have Mercy! Jimmy Fallon Gets a Pep Talk From His 'Full House' Dads

As part of the promotional push for John Stamos, Bob Saget and Dave Couiler's Dannon Super Bowl commercial (yes, there are promotional pushes for commercials now), the three former Full House patriarchs have been showing up all over the place. On Wednesday night, the trio made an appearance during the cold open of Late Night with Jimmy Fallon.

The sketch began with a pajama-clad Jimmy Fallon calling out for his dad, summoning Saget as Danny Tanner. Stamos as Jesse Katsopolis and Couiler as Joey Gladstone quickly followed. "We just heard some sad, yet sappy, heart-warming music," Jesse said.

Together, Fallon's three dads convinced Fallon that he would be great as the host of The Tonight Show. "No one can ever take that away from you," Danny assured him. "Well, maybe Jay Leno," Jesse noted. You're a smart man, Uncle Jesse.
