I hadn't heard anything about it. I just saw a commercial for it a few hours ago. I think Will Sasso is doing an Austin impression. I don't know. I hate Mad Tv, it just isn't funny to me. I'm kinda surprised the WWF didn't say anything about it too.

I think it stems from Raw having a deeper roster in terms of who they see as marketable guys. There are guys who wind up on Heat that also get a lot of Raw time (Goldust, Val Venis, even the Frenchies were on Heat a lot this summer)
