Engineers make Horrible Jokes

The integration jokes are the worst--trust me--but this comes close. Consider the following excerpt from my Fluid Mechanics textbook, which is talking about pressure waves in compressible fluids:

"These pressure disturbances travel a considerable distance ahead of the airfoil before being attenuated by the viscosity of the fluid, and they 'warn' the upstream fluid that the airfoil is coming (the Paul Reveres of fluid flow!)."

I didn't even add the exclamation point. It's that bad already.

Pendulous

Nothin'. I just like the word.
