What is the coolest or most original Halloween costume you have ever seen?

Either the 13th-century Venetian prostitute or the Potted Fuschia, both of whom I encountered my freshman year of college, Fall of 1978, during the Great Second LSD Wave. I also recall that there were an awful lot of Dead Popes that Halloween. Some of them were Screaming Dead Popes, a la Francis Bacon.

Not the best I’ve seen, but I was at a party where a guy was wrapped in a white sheet with red blotches on it, and he had a string hanging from his head.
He was supposed to be a used tampon. He was trying to be funny, but all the girls were grossed out. (Same with the guys).
I also saw a guy with a garbage bag over him with pieces of garbage attached. He was supposed to be White Trash.
Normal clothing, with socks and dryer sheets pinned all over.
Static cling. 
Had a friend in college (female) who also did the used tampon thing.
Best one I’ve seen was six guys dressed as a Viking ship. Kinda makes it impossible to sit down or use the bathroom all evening, though…
A “cerial” killer. Very funny when worn by a person with the right personality.
White Wolf

The most original one I’ve heard of was a few years back at the local Halloween contest. There were two people in the costume, which was one of the two guys dressed up as a waiter with a table apparently suspended from his midsection, complete with a covered platter. When he lifted the cover, a VERY odd entree was revealed: his partner’s head. I didn’t get to see it, but I liked the description.
A guy in New Orleans; of course, Halloween is like a pre-holiday dress rehearsal… He was dressed in a head to toe body stocking covered with tiny square mirrors. And a cowboy hat & boots & face mask covered with mirrors, too… the best part is, as he was walking down Burgundy, the ass-flap hung free.
In Jr High, I put a clotheshanger through my head and went as a failed abortion.
The early bird gets the worm, but the second mouse gets the cheese.

My friend Jim went as a flasher with a spectacular huge fake dong hangin off of him. He flashed it fast enough to be asked if it was real.
I have gone as ASH from Army of Darkness with fake chainsaw hand and gore all over me. This year I am going as the Alfalfanator…Alfalfa and Terminator combined. Looks good with the replica guns hanging off me and the goofy hair
Truly one of the best was a bunch of guys looking about the same in suits but some had blood all over them…then when you got close they had nametags like Hi I am Mr White, Mr Blonde, Nice Guy Eddie. They were the whole cast of Resivoir Dogs
During my party animal days I used to pack a camera and prowl Halloween parties collecting photos of the best costumes. I stopped this practice but I’m sure there is a marketable book in this.
On the tampon theme, I photographed one dude who had created a large labia costume out of foam sheets, with hair on top, and he was dressed as a white tampon, with a string, inside the structure. It was a huge Haloween party and he was a finalist in the competition. The judges referred to him as “the portals of joy”. I wish I could post the picture but I don’t have the technology.
