I thought Stewart Smally was pretty funny. Of course, I was a lot younger and spent a lot of time "under the influence" so...
That character was from a much later era of SNL than the NRfPT Playters. And S.S. Saves His Family is, I believe, the next-to-lowest grossing SNL-inspired movie ever. And they've had some pretty bad ones. (As well as some crappy ones that made oodles of money and a couple of good ones.)
