What is your favorite quote fom MLP:FiM?

So I know this has probably been done before but this is a special case. My school is having a Spirit Day where everyone has to wear a quote from a TV show or movie, so of course I've got to do something from MLP. Only one problem, I can't choose one. Can anypony help give me a good idea? PLEASE? My brony-ness is at stake!
