omg this reminds me of one of the most insane jokes i've ever played on a friend
it was the week before sports seasons changed in high school and everyone had to fill out that preliminary physical sheet. The day before it was due I stole it from one of my friends, who we will call Mark(his actual name), and added at the end that he may not shower with any other teammates because he only has one testicle. When we showed up for the physicals, I made sure to stand behind him in line. When it was his turn the nurse read the statement out loud, and I totally cracked up laughing. He ended up failing his blood pressure test b/c it shot through the roof. The funniest part is somehow he actually only had one ball, and he thought he had wrote it in himself.
