Worst Superpower?

Steve and I on the way back from our morning show this morning got in a conversation that went something like this:

Me: If you could have a superpower, what would it be?
Steve: (thinks) I'd want the ability to notarize anything.
Me: Nota... superpowers aren't supposed to be practical... that's why they're superpowers. You might as well have said you want to have really good handwriting....

So here's my question... what would be the worst superpower you could have? Think about it....
