Limericks at dawn

A girl by the name of Beaumont Bissell
Once accidentally trod on a thistle
She cried out in distress
"This isn't a text"
And went back to listen to Harrison Birtwhistle.

An optimistic chap called Greatrex
Had an inadequate appreciation of context
He wasn't very good with rhyme, either
And metre caused him problems as well
He still wanted to be world dictator. Whatever next!
