Halloween Costume - I have a beard, my girlfriend has blonde hair. What could we do for Halloween??

1. She wears a salt shaker, you wear a pepper shaker.
2. She wears a salt shaker, you wear a battery. (A salt and battery, get it?)
3. She wears a Robin outfit, you wear a Batman outfit. You go around saying "Wait here, Robin. I'll be right back." She says "Where are you going, Batman?" You say "To the batroom, Robin!"
