While there have been a couple of threads regarding your personal best this question is phrased a little differently. What is the longest pee you've ever personally either seen or heard. In my web surfing I have discovered many tales where, for example, a woman was in a public restroom at a shopping mall or concert where some mysterious stranger peed on and on as if there were no end to her urine supply.
So this is the time to spill the beans on the bladdergiants.
