I saw Mr. Crazy Angry Soviet Man on the way home from the comedy SketchFest last night, at the Belmont stop. He must be back on his meds, though, because he wasn't berating anyone or yelling about the injustices of the communist system. I boarded as far from him as possible, though, just to be on the safe side.
FYI, my favorite of the four sketch troupes I saw last night? "Hooray For Fun." Really sharp and funny. I actually laughed out loud several times, which is pretty rare. I can't find a website for that particular group, but here's a site for two of the three of them.
