Denis Leary And Molly Shannon Sang Some Nonsense Karaoke on ‘The Tonight Show’

In an interesting attempt to promote his new show Sex&Drugs&Rock&Roll, Denis Leary stopped by The Tonight Show dressed in character to do a bit of “Nonsense Karaoke” with Molly Shannon. Watch as the lyrics to TLC’s “Waterfalls,” Def Leopard’s “Pour Some Sugar On Me” and Ed Sheeran’s “Thinking Out Loud” get altered to address burger legalization and macaroni blubber. Both are very important issues.
