Wild West!
There's lots of ideas you could go with: cowboy, any farm animal, cyborg meets wild west (like in Doctor Who), bar maid, highwayman, bandit, sheriff, farmer, miner, Indian...
Why is Circus so popular? bleh >_< I hate clowns.
I just remember being little, like maybe 5 years old, and having to spend the night at my aunts house and she had my cousins rooms decorated with clowns. Scariest night of my life.
