For those of ya that don't know what a Limmerick is, it's a 5 line poem, usually humorous, in which the first two lines rhyme, the third and fourth lines rhyme, and the fifth rhymes with the first and second.....supposedly named for beginning in Limmerick, Ireland.
When I was young and had no sense,
I took a leak on the electric fence,
it shocked my cock,
it shocked my balls,
it made me shit my overalls.
