need ideas for button sayings(NYCC edition)

okay.. i know i carry on a lot about the Doctor...and i know there's only a hand full of Whovians in here..but i need a little help:) (if this works out i might be able to do something similar with Mutts stuff;) )
But i need some ideas for buttons to give away at NYCC that are connected with Doctor Who. The saying has to be short (no more than maybe 4 words). I plan on giving out buttons to folks i see as The Doctor, his companions and even Torchwood folks. And some to just plain give away if someone is really cool. (its handy to have something to hand out if you meet someone...Eve Myles and Euros have Rescue Kitty buttons;) ).

any ideas are appreciated! i need to get my mind working again!

hey i see people are READING this thing but nobody's saying anything!
I FINALLY got it together (I think;) ) and taught myself how to do the saying buttons. so if anyone has any ideas fire away!
