Men, Women, and Toilet Seats

I think every guy (at least every married guy) has heard at least one complaint about leaving the toilet seat up. I do my best to try to put the seat back down for Mrs. Dickster, and I think in our 17 plus years of marriage you could count on one hand the number of times I have left the seat up. However, an incident at work today got me thinking, so I want to pose an informal poll question, especially for the ladies out there.

Which is worse; a guy leaving the toilet seat up or a guy who leaves the seat down and urinates all over the seat? We will save the non-flushing aspect of the question for another time.
