Nah, not really. Creative idea. Any other Mays's running around where you were?
Sidenote: Until a few years ago, I thought Billy Mays was the famous baseball player Willy Mays from the 60's or whenever. I didn't watch much television, and I wasn't big on baseball. I just knew the guy (Willy) lived in my former hometown (Crystal River) before he died.
One girl at a party told me she'd seen another Billy Mays that night and he was better. I told her to shut her whore mouth when Billy Mays was talking. Didn't go over that hot.
Eh, not too relevant. If you dressed up as a living Billy Mays last year (like my brother did), it would be okay. This year, you would have had to dress as Zombie Mays to make it relevant. Otherwise, your costume is outdated.
