There once was a [person] from [place]
Whose [body part] was [special case].
When [event] would occur,
It would cause [him or her]
To violate [law of time/space]!

@matildalove @rgarner We've clearly read the same bash.org thread...

It's always a marvel to me,
For a pendulum hanging quite free,
Each tick and each tock of a grandfather clock
Is 2Pi(sqrt(L/g)).

I still mention this to students at that level (even though it's an approximation).

A mosquito was heard to exclaim,
"A chemist has poisoned my brain!"
The cause of its sorrow
Was paradichloro-
Diphenyltrichloroethane

[EDIT: Corrected bracketing on 2Pi(sqrt(L/g)), thanks Anton]

Wait, I think g needs to be under the square root too...
