I have a fever...and the only prescription is more cowbell

I need a Halloween Costume idea.

I'll take quality steps to offend any of what those Supreme Court types call 'a protected class,' 'dirty dirty hippie liberals' or my aunt 'right-wing nut jobs.' Maybe I could go as Senator Craig's Bathroom Caller, the one thing that could beat Jack Bauer, or a blogger.

Please guide me...I don't want to go as a 25 year old unemployed lawyer.
