A chemist named Adrain Castor
was in matters of lipids the Master.
When he brought to a boil
heavy water and oil,
he himself ended up in disaster.

When she earned her diploma in Arts,
they applauded her obvious smarts.
She went home after that
where she sat down and shat
and created a gaggle of farts.

There once was a Vicar named Brecht,
the man's speech had tremendous effect.
A bit smaller than life
he was told by his wife:
You must keep little Willie erect.

With his penis in splendid erection
it was aimed at the lady's midsection,
she said hurry, my man
stick it in while you can.
And he valued her heartfelt affection.
