Writer's Block: There Once Was a Girl from Nantucket

It's Limerick Day! Share a favorite or compose your own humorous five-line poem with an AABBA rhyme structure.
Oh, this one's eeeeeeasy!

My favourite Limerick makes me laugh my arse off every time I recite it or think of it, so I'm going to share it with you all:

There once was a preacher at King's
Who discoursed on God and such things,
But his deepest desire
Was a boy in the choir
With a bottom like jelly on springs.

What's not to love about that??? What's your favourite limerick?
