Pret-ty funny stuff, Michael!
Check out the video (above) in which Michael J. Fox jokes about Charlie Sheen on the Late Show with David Letterman.
Sounds like this was definitely all in good fun. These two are buddies from their Spin City days!
Hey, maybe Michael should help roast Charlie! We bet he could come up with some more HIGHlarity by the 19th!
Think about it, Fox!
