In case Jim Halpert's pranks and cutesy-ness with Pam on The Office don't get you all doe-eyed and swooning over the dude, actor John Krasinski's recent appearance on Late Night With Jimmy Fallon will surely set your heart aflutter.
The actor played a round of lip sync with Fallon and proved that he could do a mean impersonation of Katy Perry. Fallon doesn't do so badly himself with a powerful rendition of "Somewhere Over the Rainbow."
But the real winners are the viewers who get to watch Krasinski serenade -- while removing his clothes -- Fallon with a Boyz II Men jam. Go home Internet, today can't get better.
