flynnibus - If you got to PI, I suggest that you just give AC a try. Go in there and see one of their main shows in the lobby. I didn't like it at first when I was 17 and there with my mom in 2003 at one of the smaller shows. But when I went in 2005, just two years later I LOVED it. You just have to go with an open mind (and go to the main room) and it'll be fun.
They are actors. They might flirt with you, but it isn't with the intent that you will "pick them up." They are doing it to be funny or make other characters jealous.
