Have you ever smacked yourself in the balls?

I was just sitting here naked in my computer chair and I simply moved my hands down into my lap with the intent to rest them there, however I ended up smacking myself in the balls not every that hard with my knuckles and I tipped over out of my chair like a redwood from the pain. Discuss the times you've smacked your balls. plz.

This one time I was drinking a can of coke when some of it spilled on my pants and when I went to brush it off with the back of my hand I accidentally smacked balls. It hurt so bad I almost passed out.
