Watch: Rizzo, Schwarber perform impromptu 'Lean on Me'

Anthony Rizzo has been a busy guy of late: hanging out with DJs, shooting pucks at a Chicago Blackhawks game, visiting a children's hospital with the World Series trophy, and attending the wedding of his bromance partner Kris Bryant.

Rizzo added one more escapade to his active offseason schedule Thursday by hosting a comedy event called "Laugh-Off for Cancer."

During the laugh fest, Rizzo and teammate Kyle Schwarber began an impromptu version of "Lean on Me," which was actually a hit with the crowd and wasn't too poorly sung.

Schwarber's singing background from his show choir days may have had something to do with the quality, though.
