Jimmy Fallon Sings With Classroom Instruments | Videos

Today is Jimmy Fallon's 40th birthday, and along his road to the top, he's given us a lot to smile about — not the least of which are these classroom-instrument song renditions. Ever since he brought Carly Rae Jepsen on Late Night to sing "Call Me Maybe" with colorful xylophones and The Roots, it's become an ongoing act. He's even continued it on The Tonight Show, mostly recently with "All About That Bass" and Meghan Trainor. In honor of his birthday, let's look at his best videos.
