Chris Stapleton always seems up for anything when he visits late-night TV and he typically holds it together through those hilarious comedy skits, but Jimmy Kimmel may have gotten the best of him during his appearance Wednesday night on Jimmy Kimmel Live.

In a skit called “Wing It and Sing It,” Chris improvised a melody and Jimmy provided lyrics that he hadn’t seen before. Chris made it about halfway through what was actually an ode to John Stamos of Full House fame before he was consumed by laughter.

It doesn’t sound like a radio single, but John himself seemed to like it.
