C'mon, when somebody says the medical phrase "sperm count", who hasn't thought of The Count from Sesame Street, wiggling his way through the various internal workings of an ejaculation?
Or maybe he could be sitting at a microscope beside a bunch of Snuffalufagus porno mags and lubricant-- ahhhh shit, that would've been a better punchline!!!!! But not as weird, of course...
