"If you haven’t yet succumbed to the summer-jam joy of Carly Rae Jepsen’s “Call Me Maybe”—seriously, who are you, and who hurt you so?" Those are the words of The AV Club's Genevieve Koski, and I can't top them. It's true -- the song is infectious, but not in that have-to-put-some-cream-on-it kind of way. And now, Jimmy Fallon and The Roots have re-imagined the song in the way that only band nerds could -- with toy instruments. And you know what? It's still catchy as hell.
