One month ago, Jimmy Fallon walked out onto the stage of the new Tonight Show set at 30 Rockefeller and officially took over the venerable TV institution. Since then, the former SNL star has continued to do what he does best: reimagine R&B songs as barbershop quartet ditties, riff alongside the members of his house band The Roots, and inspire celebrities to do remarkably silly things they probably wouldn't have done next to Johnny Carson or Jay Leno.
He's certainly welcomed some heavy-hitting music acts — his first month alone, he's brought on U2, Arcade Fire, Beck, Lady Gaga, and Rick Ross — but we've tuned in primarily to see how Fallon's goofy, enthusiastic sense of after-hours fun would fare on the crown jewel of late-night shows. The answer: like a charm. Here's a handful of the host's best moments from his first month on the Tonight Show. Long may he reign.
