Mark was an incredibly funny actor (and totally still is). Any part you handed him--mime, priest, colorizer, beach nerd--were much improved by his presence. We did a lot of sketches together and I was lucky enough to get tapes of some of them. I want to share them here.
Now, here's the thing; the show announces them as a new improv group, which is exactly the opposite of what they were. They were a sketch comedy group that wrote, honed and rehearsed the material before it got before an audience. But people were turning the term "improv group" into a generic phrase for any comedy team, like the word selfie suddenly means any photograph of yourself whether you took it yourself or not. Also, please excuse the quality. it's a 30-year old VHS tape, that was a copy itself before I digitized it at home.
