third nipple?

tonight as i was prepping for slumber, some people walked past my window. my shades were drawn so dont bother asking for a physical description. as they passed, i heard this:
"so lets say..umm...would you rather have a third nipple or an extra testicle?
i didnt get to hear the response as it was muffled by the doppler effect. BUT, 5 minutes later i heard the same pair on the return voyage:
"NO, you cant cut it off! its a third nipple you have to keep it on for at least a month!"

i would have opted for the extra nut, but thats just me.
