On Friday night's episode of "Late Night," Jimmy Fallon made time for his weekly Thank You Notes, where he writes little letters to the things in the world he's appreciative for.

This week saw him thanking home run derby champ Prince Fielder, aluminum foil and even monkey bars for enhancing his life.

The real fun is watching Fallon and announcer/sidekick Steve Higgins have such a good time singing, though. Dare we say it: this may be the goofiest Thank You Notes bit yet.

Watch the full clip above, and check out the thank yous of yore here.
