There was a young man from Japan
Whose meter just never would scan
When told this was so
He said yes I know
But I always try to fit as many words in the last line as I possibly can

Little Willie, Pair of skates
Hole in ice, Golden gates

Willie fell down the elevator, Wasn't found till 3 days later
Then the neighbors sniffed Gee Whiz! What a spoilt child Willie is!

God in his wisdom made the fly, and then forgot to tell us why

If Noah had been truly wise, he would have swatted those two flies

I had written to Aunt Maud, who was on a trip abroad
When I heard she'd died of cramp, just to late to save the stamp

I know more, but they're all a bit longer.
