Normally Kermit the Frog feels a little insecure about his green color, but Jimmy Fallon was able to help Kermit feel more comfortable in his own skin. 

Kermit was singing 'It's Not Easy Being Green,' when Fallon walked out onstage dressed completely in green to celebrate St. Patrick's Day. He told Kermit that St. Patrick's Day is the easiest day of the year to be green, and the two finished the song together.

Watch the video above, and see the duet for yourself.
