Angel... or Devil?

In a few hours I am going to be on tv and I know that this is a very important day for my parents because they are very excited to find out if I am a boy baby or a girl baby. I must admit that I am also a tad bit curious myself... So, my dilemma is this: should I be a good little baby and make things easy for them, or should I be a naughty little baby and keep my legs closed, just because I can?
