Once, I was at a pizza place with some friends after a party. They were up ordering, so I started messing with the condiments. You know, putting some pepper on a napkin and putting it in the salt shaker, that kind of thing. I've had some practice with this, so I'm pretty fast and discreet, and nobody notices. Everyone messes up their food, I laugh, etc. They're pissed at first, but they forgive me because they're my friends, and i fix everything before we leave.

However, about a week later, I go to a pizza place. I try to put some parmesan cheese on my pizza and salt comes out.

A more "instant" thing happened when I was standing off the side of a soccer goal. I tried to peg the goalie in the back (with the ball) but it bounced off the post and hit me in the forehead.

Has anything like this ever happened to you?
