In the military, you're incessantly suffering random piss tests. One time, I got called into one immediately after having hit the head. They basically have you in their care until you submit your work for the test. After having kidney surgery, I was confident in my ability to pony up, so I told the sergeant overseeing us that I should be okay, in spite of having already delivered so recently.
I drank a quick bottle of water and went to the head with the sergeant and a group of about 5 other Marines. We had to turn so he could see our junk while taking the test. I called on my ability to pee at a moment's notice and supplied enough to satisfy the requirements of the test. I victoriously proclaimed, "See? I got skills!" The sergeant laughed. While escorting us out of the head, he walked beside me and gave me this order.
"Listen up. NEVER make me laugh while looking at a guy's junk again, understood?"
In hindsight, it was a most appropriate response.
