I was regularly watching SNL at that time, but I don't recall Gilbert on the show. I don't consider myself a fan of his, but I don't dislike him. I never paid much attention to him and only saw (or heard) him if he happened to be in something I was watching for other reasons. He is funny, though.
I do remember a stand-up routine of his where he talks about the French deciding to sell water to Americans. Very funny, especially since it is factual! When I grew up, there was no such thing as bottled water, believe it or not.
Affleck!
