This one will always remain my favorite encounter.
"Hey Chris, mind doing the Horseman sign with me?"
"Naw man, Horsemen are dead." (this was during the Revolution days)
I was also laughing (as in, make fun of) at Sylvain Grenier when he threw a hissy fit because I found a blade on the floor backstage.
Also, Pierre-Carl Ouellet called me Dave Hebner during an IWS promo. (Bakais was Earl)
A bored Steve Corino doing his best to maintain a conversation. Just the fact that a former NWA and ECW world champ was trying to keep my attention was funny in itself.
A.J. Styles offering me gum the moment I meet him.
Chris Daniels, introducing himself.
"Hey, I'm Chris Daniels, what's up? Call me Chris."
(another guy) "Heh, can we call you Curry Man?"
"You can, doesn't mean I'll answer you."
Being face to face with Perry Saturm's cross-eyed looked just screams "I'm a goof."
