I love limericks, they are very cleverly written poems.
Just a few examples:
A gourmet dining at Crewe
Found a rather large mouse in his stew.
Said the waiter, "Don't shout
And wave it about,
Or the rest will be wanting one, too."
There was a young fellow called Binn
Who was so excessively thin
That when he essayed
To drink lemonade
He slipped through the straw and fell in.
'Tis a favourite project of mine,
A new value of pi to assign.
I would fix it at 3,
For it's simpler, you see,
Than 3 point 1 4 1 5 9
And a last one (watch out for the pronunciation!!):
There was a young lady from Slough
Who one day developed a cough
She wasn't to know
it would last until now
I hope the young lady pulls through!
Indeed, I think it will "fox" my students.
