Archaeopteryx

There existed a very strange chap
Who created a game with a map,
It was all about fish
And it looked very swish
But it was really a pile of crap.

There once were some folk who wrote limericks
For rhymes they were frequently in a fix
It became such a feat
That I've started to cheat
And am ending this one — archaeopteryx.

There once were some folk who wrote limericks
About intertextual metaphysics
They were over two-thirds
Full of very long words
And they scanned as iambic anapaestics.

There once was a yak in the bath
And an elephant under the path
There were eggs in the trees
With a plate of cream-teas
Oh, this limerick's good for a laugh.
