I had a one night stand where the guy warned me he had only one ball. My immediate (in my head) reaction was I would not have noticed.

They shift around on their own and sometimes one or both hide for some reason, and honestly I respect the hell out of such a chaotic organ, but they are purely unreliable. Just imagine going through life thinking testicles are stagnant and neat, two nuts in a skin sack, only to find out half the population has these roving jizz pebbles constantly on the move. Our word for 'planet' comes from the greek word for 'wanderer,' and so should testicles have been named. They wander the groin as the trepidation of the spheres rolls planets across our skies. Never still.

So I guess they're okay. He didn't want me to touch his ball anyway.
