If you can't beat them, join them :)
Find the one who stares the most, walk up to him and say 'You win, let's have another contest.'
Or, when you see freaky stares, jump and scream, or make a horrible expression, as if you've seen the ugliest thing ever.

On a serious note, the best way to deal with it is to... just ignore, and have a good time.

Hahaha, Captain, your picture justifies your display picture spot on! Wallah you're hot!
