John Krasinski and Jimmy Fallon went head to head Tuesday night in a lipsynch battle on Late Night With Jimmy Fallon, rocking tunes from Melissa Manchester, Das Efx, Boyz II Men and more. The pair synch their hearts out in a tug-of-war for bragging rights rife with melodrama and comedic gold. Jimmy Fallon attempted to put Krasinki’s chances to bed with his take on a 1984 performance of “Somewhere Over The Rainbow” by Star Search champion Sam Harris. His passion-filled interpretation was definitely a punch to the gut, but the show was far from over. John Krasinski had something even bigger up his sleeve, dropping a show-stopping performance of Boyz II Men’s “I’ll Make Love To You” – a rendition so soul-stirring Jimmy Fallon couldn’t resist getting in on the act, making the last song of the battle a duet and John Krasinski the clear winner.
