A guy goes into a public washroom and has to use the only available urinal, between two elderly men. He glances to his left and sees the guy pissing, but there are two streams.

"What the hell is that?" he asks.

"War wound. I took a bullet in the penis in North Africa. They were able to save my dick but they had to leave two holes"

Then the guy looks to his right and sees... three streams!

"What the hell is that?"

"War wound. Germany, bullet in the penis, left three holes."

The two veterans then look over at the guy in the middle and see... 12 streams!

"War wound??"

"Naah, my zipper's stuck"
