Great, now somebody has to change that "you owe me $20" picture.
Look him in the eye and tell him he's only worth 19.99, but you'll give him $20, see if he goes for it. Use this sold Ebay auction as leverage -http://www.ebay.com/itm/LOU-FERRIGNO-Autographed-Poster-23-x-35-THE-HULK-Avengers-Comic-Book-Character-/322204794184?hash=item4b04e6fd48%3Ag%3ABpwAAOSw1KxXM7~4&nma=true&si=sFt1U06pWpGntEf28xNxMYQZv%252BA%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557 .
there it is...
So I have an original Lou Ferrigno Hercules movie poster I've had for years. I'm at the Pittsburgh Comic Con. Big Lou wants $80 to sign!!!
I would wipe my ass with it and leave it on his table.
I'd just give him a blank look and say, "Keep it."Then walk away.
