Have Mercy! Watch The Epic 'Full House' Reunion On 'Jimmy Fallon'

Cut it out! You don't quite realize how much you've missed Full House until you see the cast reunion that aired on Late Night With Jimmy Fallon last night.

And it was perfect in every way possible.

John Stamos, Dave Coulier, and Bob Saget graced us with their presence in a sketch on the late night show, where they all were in character, including Uncle Jesse in mullet mode and Uncle Joey in a full-out '80s Cosby sweater.

After having a nightmare, Fallon calls out, "Dad! Dad!" (from Michelle Tanner's bed) and then like magic, Danny Tanner walks through the bedroom door, with Uncle Jesse and Uncle Joey in tow.They were all there to ease Fallon about making the move from his late night slot to his new gig on NBC's Tonight Show.

Uncle Joey brought back his many impressions including Popeye and Ranger Joe and Mr. Woodchuck. Uncle Jesse delighted us with his tagline "Have Mercy!" Then they sang the "Teddy Bear Song" to Fallon to calm him down. (The last time we got to see Jesse & the Rippers perform was on Fallon's show back in July.)

But, where were Michelle, Stephanie and D.J. Tanner??

The Full House reunion will continue at the Super Bowl on Feb. 2 in the form of a Dannon Oikos yogurt commercial. A teaser commercial was released with hints at more to come on the big game day. Hopefully, we'll get to see the girls in that one!
