I'm not surprised to see Zach leave. His signing seemed like a publicity stunt to me - if you hire a guy with only one leg, the mainstream media is sure to notice. I was like
when i saw his first WWE match, but his act grew old very quickly. And he had his own T-shirt made as well.
However, it would have been interesting to see him enter in the Royal Rumble. The rules state that to be eliminated, you have to go over the top rope, and
BOTH feet must touch the floor. Technically he couldn't have been eliminated...
