Well, if he uses capital letters, decent spelling and properly structured sentences he might be ok
EDIT: Seems i was a bit late with that one.
Anyway, in most cases, i would not put it on a CV. But If i was an employer (i am actually), i would not bin it because he had that on it, i would wait to meet him. In fact, i would probably get on well with him (although I'm not a WOW kind of guy). I'm guessing it had other things on it, no? If the only thing he did was WOW, then i might see things differently.
