Loony Limerick Competition #4

It's time for the next instalment of this wacky limerick contest. All you need to do is to think of a last line and leave it in the comments section here. There is a (secret) judge monitoring your entries and waiting to choose the best effort. Extra points will be given for humour and creativity.

• You can enter as many times as you want to
• The competition closes 48 hours after this post is published
• The fifth line must rhyme with "cow" and "how"
• The judge will not be swayed by bribery (I think!)

It wasn't the sow; it wasn't the cow,
The farm was stinking; no one knew how
The farmer blamed aliens whom no one had seen:
"They dumped their crap here, all shiny and green,"

The judge of Loony Limerick Competition #3 was Old Tom Wigley and he chose Akelamalu as the winner with this stirling effort:

Fella with a red suit and bushy beard, said his name was Santa,

Stole a gleaming black-eyed stallion, and rode it at a canter

He declared he was late to deliver the presents,

So he gulped down a dinner of brandy and pheasants

Then was immediately sick on the porch in a planter.
