Watch Jimmy Fallon, Adam Levine do impressions

Fallon fans have long known that he's a master singer sound-alike, thanks to his many spot-on performances as Neil Young and his History of Rap installments with pal Justin Timberlake. But as it turns out, Maroon 5 frontman Levine is an impressive impressionist, too.

Levine proved that early on as he tackled kids' classic "Head, Shoulders, Knees and Toes" in the style of Frank Sinatra before delivering his equally remarkable rendition of the "Sesame Street" theme in the style of Michael Jackson.

Be sure to check out the full clip to see how Fallon delivered as Dylan and to hear what song he performed as Iggy Azalea — and don't miss the one jam he shared with Levine.
