Which one of these is not like the others?

Zachary Levi, the sexy nerd from the show Chuck. I want to make out with him and his succulent, pouty lips.

Ade Obayomi, a sexy all star on So You Think You Can Dance. Too bad for us, ladies, this delicious milk chocolate stud likes boys.

Twitch, also on So You Think You Can Dance as an all star this season. When he dances hip hop, friends, you will quiver. So hot! I want to take a bite out of this espresso skinned hottie.

Dave Scott, sexy choreographer on So You Think You Can Dance. Look at this sweet mocha prince in his pea coat. Yummy!

So, did you figure out which one of these is not like the other? If you guessed Dave Scott because he's wearing a hat you are SOOOOO right!
