...the physics of urination....

Dang, Just when I think I have my lesson plans all organized, this comes along.

Just when my kids were learning the law of universal gravitation.....

An average of 21 seconds with a standard deviation of 13 seconds? Sure.

Who can forget The Flow-Enhancing Urethras' opening act for The Sex Pistols in '77? EPIIIIIC!!!

If you're older, it takes about 40 standard deviations longer.

I thought the Law of Urination stated that the length of the line for the men's room was equal to the number of beers you've had multiplied by the number of minutes already spent on the game clock and then divided by the current point spread.

Scientists were hampered by the fact that for some mammals it takes longer when other mammals are in the room.

I've been studying this issue for something over 60 years now and have concluded this is one area where practice does not make it easier.
Especially about 3 a.m.

I see no flaw in JD's equation.

How big are we talking with "the design of scalable hydrodynamic systems based on those in nature" - Belagio fountain sized urine streams?

Which one of We Guys haven't boasted about "the increasing urethra length of large animals"?




they need to elucidate a beer corollary.

NOOOO! My kids already have trouble with Newton's Law of Universal Gravitation!

Frank, that was my first thought. A mean of 21 with a SD of 13? That gives a confidence interval of about .02

And put the damn seat down too!

When statistical process control makes its way into urology, things have gone too far.

Consultant: Was that normal or special variation?

Engineer: Oh, piss off.

Consultant: Exactly!

Omni, was it a bell curve?
