First up was Molly Shannon, who sang “Waterfalls” by TLC. The chorus, however, went from “Don’t go chasin’ waterfalls” to “Don’t throw Jason’s Barbie Dolls.” Just because. Next up was Denis Leary, who performed “Pour Some Sugar On Me” by Def Leppard. His chorus became “Ask your sister for peas in a baseball glove / Play some Boggle with Jeeves and his hairless pug.” Finally, Fallon took on Ed Sheeran’s “Thinking Out Loud.” Get ready, because it’s super weird. ### A Photographic History of Ed Sheeran and Taylor Swift Being BFFs  Ed Sheeran poses with Taylor Swift backstage before his sold-out show at Madison Square Garden Arena on November 1, 2013 in New York City.
