Why no Michael J Fox jokes/episode back in the day?
Matt and Trey went to town on Christopher Reeve with a whole episode around him, stem cells, fetuses you name it. However Fox was involved in the Stem Cell thing too, later becoming the main celebrity advocate after Christopher croaked and also had a rather funny ''condition'' (he shaked).
I was waiting for them to make an episode about him back in the 2000's but this never occurred. Really I was surprised, especially after the 2006 controversy where Michael J Fox made stem cell research a ''political issue'' and went on tv with no medication flopping around like a fish on a chair. They really missed an opportunity with that one.
