Is it normal to laugh at a guy cracking his nuts on a rail?

I would just feel pain

I think it's comical and painful at the same time! I'm a guy, I think it's funny as long as it's not me, but at the same time it also hurts to see it.

It is normal, but just imagine how it feels! And then to try and rub anywhere without anybody seeing it's your nuts that hurt!

In a laddish peurile kind of way, it is fall about laughing amusing unless he is really injured. It's a man thing.

Once when I was younger I hit a dude in the nuts with a see-saw. I felt bad but it was still hilarious.
