Does anyone recall a limerick that has to do with NASA, the Apollo spacecraft,

is short lived. I suspect the limerick has been around for awhile.

One of these?

There was a young fellow named Cole
Who ventured too near a black hole.
His dv by dt
Was quite wondrous to see
But now all that's left is his soul.

A black hole isn't much of a sight,
For intense gravitational might
Makes it dark, I recall,
Because nothing at all
Can escape from it, not even light.

A black hole, gravitational well,
Casts a wide ineluctable spell.
You may cross its horizon
Without realizin'
You're bound for extinction pell-mell!
