Before this mini-man on the microphone was up late cracking jokes to a live audience, he was just another funny fella repping a mullet in Bay Ridge, New York.

This singing star is best known for his quirky comedy, topical impressions, and hilarious musical stylings — which he showed off effortlessly in an audition that launched his career. This weekend gig was just the beginning … he caught the bug for the big screen but eventually shifted back to late-night entertainment.

Now, you can catch him letting his hair down in sketches and interviewing some of your favorite celebrities as a television host.
