What's the best Halloween costume you have ever worn or seen someone wear? Did you/they win a prize for it?

my best halloween costume was a referee but this is the best i've ever seen someone else wear. i hope he won a prize!

In the 10th grade i was the sugar plum fairy. I won an award for most beautiful costume.

When I was married, one Halloween my children and step children dressed as the Brady Bunch kids. There were 5 of them so the oldest girl's boyfriend joined them. With 4 boys and 2 girls it fell on my youngest stepson to go as Cindy. He was adorable! They all got ribbons at the school festival for best group and "Cindy" got an honorable mention as best little girl's costume.

My friend dressed up as a giant penis it was too funny

I saw a guy wearing a super realistic Pyramid Head costume from Silent Hill. It was awesome. Here's a pic that somebody else took for reference: http://www.coolest-homemade-costumes.com/images/coolest-pyramid-head-costume-39887.jpg

I saw a young lady dressed up like Xena once at a Block Party. Looked just like her. Wow! I thought it was really Lucy Lawless.

Oh Oh Oh! I once went to a Scottish theme party (St Andrew's day is just after Hallowe'en - so there is tenuous link). Anyway, a guy came to the party with a certain item of ladies' underwear on his head - he said he was dressed as a major city in Scotland: 'Ead-in-bra! (Edinburgh)

These are some of the best I've ever seen. Take a look! http://www.youtube.com/watch?v=akNJ6S2UqsE http://www.youtube.com/watch?v=cQvfnz4Zd1k&feature=related

I love a skeleton costume with fake red bood accually running through it, but it did not win a prize.
