I need a Samhain (halloween) costume

[pylon_boy]

So at my church we're going to have a masquerade party. I need a costume. So far I have turned down in no particular order...

Shoulder angel (my date didn't want to be the shoulder devil)
Mr. Rogers (I don't want to shave off my beard)
Unibomber (I don't want to shave off my beard into a porno stache)
yet to be creepy Michael Jackson
plus many other really bad ideas.

I need to be presentable because there will be children at the event as well.
