Wow. That's not even one of the more "popular" John Waters films-- that's some seriously underground cinema right there. You have good, if twisted, taste. (I loved Jean Hill as Grizelda, the maid.)
I love her! I loved Edith Massey more though.
I've been fortunate enough to meet John and Mink on a few occasions. They're big fun and hilarious. John married two friends of mine a few years ago- just flew in for the day. That was a blast. We also had him as our special guest for the Chicago Underground Film Festival a few years ago.
