I pretty much have watched every Q&A thing that Smith has on Netflix. My personal favorite is Too Fat for 40 mainly because that story is just so convoluted and hilarious. Plus his imitation of Bruce Willis is spot on. And... oh yeah, he only answers the one question.
Mewes to me was never very funny, but I can understand the appeal. I'm glad he finally got off the junk, though. I just hope he stays that way. From what I gather, this isn't the first time he's tried to stay clean. That porn game they played at the end was pretty hilarious, though. I think it was called "Let Us ***", but I could be wrong.
