I agree that Jay and Silent Bob are probably their funniest in "Mallrats", although they're both pretty awesome in "Jay and Silent Bob Strike Back" too especially with the Bluntman and Chronic sequence
I just rewatched Jay and Silent Bob and haven't watched the other movies in a long time and was surprised just how much Jason Mewes did in that one.
After his demons Jason looks like a different guy these days. But if Kevin's "muse" can get him to squeeze out one more...
I was a clerk when the first one came out so that movie had special meaning for all of us when we discovered it.
