I love The Roots. I am mildly indifferent to Fallon. I find the covers of "Call Me Maybe" lame.
But their classroom instruments version made me happy.
I look forward to seeing Carly Rae Jepsen on VH1's Top 100 One Hit Wonders of 2010s.
Edit: I love how Black Thought can't keep it together at 2:35.
Edit 2: At 1:40, she looks like she is having a genuinely good time.
