What's the most obscene Halloween costume that you have ever worn?

I made a fake peg leg for Randall once, so he was a pirate and I was his winch. We won first prize in the costume contest at a huge work-sponcered Halloween party we went to at Old Tucson Studios! I don't have any pictures of us then. But I did find this one pic of another crazy couples costume we dressed us as once:

I stuck my pair of slippers (that looked like cowboy boots) on the end of Randall's stumps and dressed him like a cowboy. Then I dressed up like a horse and told him to "...ride me all night long!".
