urx unit loader Watch Jimmy Fallon and Kermit the Frog sing 'It's Not Easy Bein' Green' on 'Tonight'

Kermit the Frog stopped by “The Tonight Show” Monday (March 17), where he sang his classic “It’s Not Easy Bein’ Green” with host Jimmy Fallon — because on St. Patrick’s Day, it’s the best day to be green.

Below, Kermit talks about his “nude scene” with Tina Fey where she licks him and sticks him to a wall — but he’s always nude, so it’s OK.

Kermit also shows a clip from the movie featuring Ricky Gervais, who he says brings “an incredible, edgy humor” to the Muppets.

“Muppets Most Wanted” opens Friday (March 21) — check out Zap2it’s own interview with Kermit and Miss Piggy.
