As part of my Kidney Transplant, there was a catheter placed from the new kidney into my bladder. Yesterday was removal day. What they do is go up the pipe, grab the thing and gently YANK IT OUT!

I had a male nurse preping me for the procedure. As he starts to do his job, cleaning with the iodine and such, he says "it's not uncommon to get an erection while I'm doing this" I told him I didn't and wasn't going to. He said "I was talking about me."
