Damn--this is tough. I may have to go with not the guy who has was the best sourpuss (too tough to decide), but rather who i'd like to see win . . . no, wait . . . who i'd rather see lose so he can be a sourpuss . . . or maybe . . .
What makes it really tough was i loved sourpuss Bret Hart in WCW when he wore the steal plate on his chest under his t-shirt and Gold-turd speared him and got KO'ed. "Who are you to doubt El Dandy?!"
Loved Shane Doofus's runs in ECW too.
But the other 2 are such icons of SourGrapedom . . .
