Neutered?

Jed was watching the Simpsons (I know... good mothering) and heard the word "neutered". The conversation went something like this.

Jed: Neutered? Is that where they cut off your rude bits?

Me: The penis stays, the balls get cut off.

Jed: I wouldn't be able to wee.

Me: Are you listening? The penis stays, the balls go.

Jed: BUT I LIKE PLAYING WITH MY BALLS!

Me: I know mate. But don't worry, it's not likely you will ever be neutered!
