I didn't even know he had a podcast! I always liked Mr. Rowdy - he was the first "heel"wrestler I knew about as a young child - and I should probably go check out his podcasts, assuming they are archived and available.
I never really saw Piper as a Heel, at least not any more than Stone Cold, but I don't really follow WWF. Seems like Undertaker and Kurt Angle were more heelish than Piper, but it's not like it's a bad word or anything.
These smart-mark fuckers always want to get the "inside scoop" on "the business" so they can talk shit and cry into thier crusty man-boobs about anal screwjobs and whatever.
Every so often you get awesome commentry on in-ring crimes like that New Jack fella but that's not really from podcasts
