I was an undercover Time Lord, who happily zapped things with my sonic screwdriver.

So there you go, you could just go in jeans and a t-shirt and be Joe the Plumber.

*To clarify, this wasn’t because ANYONE thought that JTP actually represented “real America” but as a highlight to the absurdity of the whole thing.

Close. I’m going as the jackass who makes his house look dark and empty all night because he hates answering the door only to be shrieked at by demanding dipshits in stupid costumes. It’s like being harangued by Jehova’s Witnesses, only with more pop culture references.

Just use a name tag or place a cardboard sign labeled “unreal American” on yourself and you’re good to go. :)

Here’s some costume ideas for ya:

One year my brother safety-pinned a bunch of clothes on his outfit and went as “Pile of Dirty Laundry”. Another friend wore a t-shirt that said “I’m fucking Harry Potter”, which was funny on two levels.

Cannibal – clothes you’re willing to destroy, including and apron and kitchen/BBQ implements. Lather on the fake blood. (either mix red food coloring with clear dish soap or white corn syrup. The dish soap washes out easier but be careful around your nose and mouth) Answer the door holding a covered pot or roaster with suspicious stains.

Suicide salary person: person suit, brief case with various papers sticking out and cutting wounds to neck and and wrists. A neck tie as a noose with the proper neck bruising works to.

Accident victim: copious bandages in various places with a liberal amount of fake blood. For added fun, have a medicare claim stamped “DENIED”.

Various undead: Modern Vampires – black clothing pale foundation, dark around the eyes. Also passes for various shades of goth and punk.
Modern walking corpses (since zombie is a slur) – any clothes you won’t miss and gratuitous fake blood wounds. If you have green, grey or other such colors of face paint, apply to skin. Darken the hollows of the skull for both types of undead for the proper effect. (I have no idea why this shows up in bold type. Sorry)

If you have any sort of uniform or some sort of clothing indicative to a trade (scrubs, overalls, coverall, etc) add appropriate props and go as a members of said profession.

If you know any people who are part of the goth/punk/emo/hippy etc subcultures, as to borrow something and have them make you up for the evening.

Cop out and buy one of those shirts thats says, “This is my costume”.

Glue, staple or quick stitch zippers, button and fabric to some old clothes and go as an unfinished costume.

Sports fan : wear some merch from a certain team.

Volunteer to let a friendly stage/fx make-up enthusiast make you up.

That help?
