3. Who
http://www.youtube.com/watch?v=W3WYWiqkL3M A cheap excuse for Vince McMahon and Jerry Lawler on commentary to perform a full Abbot and Costello routine, "Who" was billed from "Who knows where" and lasted no time at all before the company pulled the plug on the gimmick. No surprises there. The wrestler known as "Who" was in fact Jim "The Anvil" Neidhart under a mask during a short lull in his career. Thankfully he found his feet and found a more useful proper noun to use as his name when he returned to being known as Jim again just a few weeks later.
2. Terra Ryzing
From the same school of wrestler names as Justin Credible, Terra Ryzing was an early god-awful ring name of the man we would all come to later know as Triple H. Yeah, ok, he only used the name for a few months before he became Jean-Paul Levesque and then later Hunter Hearst Helmsley, but how could you resist putting together a list like this and not including that ugly name in there? I think we can all say that he did ok for himself despite this temporary handicap.
