Heheh, Robo Wilt! The episode "Make Believe it or Not" comes to mind. His "imaginary" self had a bionic arm. What'd he call it, his "Arm of Doom" or something? lol...
I wonder if Wilt would go through with something like that, though. I've heard of many people, and even know a few, who have had some disability and when asked if they'd take the chance to be "whole" again, they wouldn't take it because they've already learned to accept their disability and it would be hard to get use to the new change. Wilt somehow seems to be that type. He's too humble to accept a "gift" that big if it were offered. But then, if someone said something like "Will you do it for me?", then, maybe.... Yeah, he'd probably do it then.
