Snapple koozie!

On Tuesday night, Jimmy Fallon had Molly Shannon and Dennis Leary on the show to play a game of "Nonsense Karaoke," where you belt out complete gibberish lyrics to the melodies of popular songs. The result is incredibly entertaining and hilarious.

Dennis Leary dresses up in his rock-star threads to do a little "Pour Some Sugar on Me" by Def Leppard. Jimmy serenades the crowd with a nonsensical version of Ed Sheeran's "Thinking Out Loud." But holy damn, Molly Shannon just kills it with a balderdash-tastic rendition of "Waterfalls" by TLC.

Don't go chasing waterfalls, folks. Because "grammy gets the shivers and the shakes after kung fu."
