GM's worst punishment

[General Pain]

I've been reading loads of posts here and since I myself am going to be GM this weekend, I was hoping for some inspiration from my fellow posters.

What is the worst any GM has ever done to your character?

I'd guess this would bring many horrible memories, and I'd like to hear/read them.

PS: For players who are playing in my campaign,you know who you are, don't worry your little heads about this........
