The always hilarious Julia Louis-Dreyfus stopped by The Tonight Show Starring Jimmy Fallon on Wednesday, and in addition to promoting season four of Veep, which premieres this Sunday, Julia also indulged Jimmy in a hilarious Game of Whisper Challenge. Basically, the two had to take turns wearing **ise-canceling headphones while the other said clues out loud - and the results had all sorts of ***ual undertones. Julia had a plethora of guesses - including "sausage penis" for what was ultimately "salted peanuts" - and when she tried to help Jimmy guess the Bru** Mars lyric "Uptown funk you up," he was so offended that he just said, "You can't say that!" Watch the video above **w for some serious laughs, and then check out more of the funniest moments from Jimmy's show.
