Watch Jimmy Fallon Drunkenly Butcher This Guns N Roses Song

August 6, 2018

From the looks of things, late-night host Jimmy Fallon was feeling no pain while dining at a Hamptons restaurant this past weekend. 

According to TMZ, Fallon's impromptu a cappella performance took place at the Palm in East Hampton, N.Y. The comedian -- who has delivered humorous impressions of other iconic rock singers on The Tonight Show Starring Jimmy Fallon in the past -- can be seen serenading a fellow customer with a particularly piercing rendition of GNR's breakthrough hit.

We won't tell you what song it is, 'cause that's all part of the fun! BTW, eyewitnesses say Jimmy appeared pretty sloshed with his wifey. So, yeah ... ya might have trouble deciphering some of the lyrics. WATCH IT BELOW
