For a costume, maybe you could dress up like a bunny (kinda like Reese Witherspoon in "legally blonde") I think the guys would get a kick out of that!
Talent : how about the water glasses (like on "Miss Congeniality") and I'm sure the guys would think it would be hilarious for you to dress in a costume like Sandra Bullock did in the movie!
(No, I don't watch a lot of movies!
)
