Shouldn't the Naked Cow be the one suing?

I see the Naked Cowboy is suing the Naked Cowgirl for stealing his idea and sullying his name. The Naked Cowboy is the guy who plays his guitar in Times Square wearing little more than his birthday suit.

But wasn’t the Naked Cow really first? Didn’t the Naked Cow perfect her act long before Robert John Burck thought of donning his birthday suit to draw crowds on New York’s busiest street corners? What do you think? Doesn’t the real cow have the moral high ground here?
