This morning, a story in the British press included the following stupid limerick:

An insect was heard to complain
That something had killed off its brain.
The cause of its sorrow
Was para-di-chloro-
Di-phenyl-tri-chloro-ethane!

...and that got me started.

A triceratops, name of Wright
Once challenged a Rex to a fight.
The tyrannosaur
Walked off, a bit sore,
But Wright's just a big coprolite.

Old Ida, part monkey, part cur
They're calling mankind's ancestor.
Tho Genesis says
It took God six full days
How long via Ida? Not sure.

LGF sez, the final solution
Can be found in the word 'evolution.'
Disagreeing with Chuck
Leaves you shit out of luck
You get banned and there's no absolution.

There once was a lady named Bright
Whose speed was much faster than light.
She set off one day
In a relative way
And returned on the previous night!

There once was a Stego named Tex
Who wanted to mate and have sex.
He gave a loud roar
Near a Tyrannosaur
And was later found inside old Rex.

Your turn.
