Brothers shield your eyes, ladies close your blinds ;)
1. A Sense of humor! One of my favorite scenes in a movie is when Heath ledgers character busts a move and a tune in front of the school to woo Cat back... **sighhhhh** aaaaah Heath Ledger... He and Warren double for great smiles, another thing to add to my list.
2. Confidence. NOT someone who is full of themselves. I think Will Smith has mastered this to a "T". All the other little goodies like his smile and arms don't hurt either of course :)
3. An accent like these musically blessed boys from England. Any accent will do.. well almost any. I'm not sure my knees would weaken with a Russian accent.
