Hey, Ryan! Actually, Bill did agree to a cameo in GB3; but, it was SONY Pictures who punked out on the deal. It upset Dan so bad that he moved his offices off the Sony Lot and to some other location. Right now, though, I think Bill is the reason NECA can't get the likeness rights to produce the action figures of the GB...and for THAT I wouldn't mind smarting off to him.
Glad everybody likes the story about what happened that day! It was fun, and I'm still not over it. It was great!
