This didn't happen to me, but a bloke I used to play rugby with.
Over the summer break, Ian (as his parents named him) had been sitting in the local football field with his mates, clambering on the goal frame and having a laugh. A group of girls came along and boys being boys, they started to show off. Our hero took a fit of bravado and decided he'd hang upside down on the crossbar and try and chat up one of the girls.

As he moved backwards, his legs slipped off the bar and he fell, to drop to the ground in agony. One of the little hooks to attach the netting had spiked through his sack, after passing through his jeans like they weren't there, to rip a 4 inch gash into it and to pop one of his walnuts out, which couldn't be saved.
He missed most of the following season recuperating and UI don't think he was truly the same again.

Can this be true? I feel queasy and had to lie down. Did he get to keep his knacker in a little jar beside his bed?

I don't know if they let him keep it, but I doubt he would have asked.
He gave me an odd look when I asked but didn't say yes or no.

I like to think they did, it became sentient and he now has an independent adjudicator to help make his decisions.

That could be a fabulous Dr Who episode. Balls in the jar making plans to destroy the earth! Giggles.
