You know who was totally awesome? Gruber (a.k.a. Dave Allen - you may know him as Principle Russo on Freaks and Geeks).
He was with the cast of Cinematic Titanic when they were in Milwaukee. They had two nights and my friend and I went both nights. The first night was my friend's first exposure to the "World of MST". The live performances were excellent (with the exception of TV's Frank... but that's another story). One of the standouts of the night, though, was Gruber. At first, he acted more like a roadie, setting up mics, telling the audience it was only going to be another couple minutes, etc. He did some very funny standup and he really got into interacting with the audience, etc. Oddly enough, he seemed to be the hardest working cast member, trying hard to be original and not to be scripted.
The second night we were waiting in line to get in (having stopped for Chinese food first) and Gruber was standing outside smoking. I called over "Gruber! You rocked last night!" (He, quite literally, 'rocked' - he accompanied Weinstein on the iPad). He actually walked over to use and started a conversation! He was funny and VERY nice. Out of nowhere, he asked if we were thirsty. Thinking he was joking, my friend said she'd love a hot chocolate. The two women in front of us turned and said "Us too!" I replied with "I'd love a coke." We all laughed and Gruber went inside. We didn't think anything of it, but he came back out about five minutes later with three hot chocolates and a can of Coke! We were stunned! About 10 minutes later the line started to move and he told us to enjoy the show then stood there welcoming people into the theater! What a guy!
He continued to be the highlight of the show for us. Even though we paid to see the MST folks, Gruber was a great treat!
