the Leprechaun Murders the Fairy

The leprechaun, the unicorn, or the fairy?

... And what did they do?

The leprechaun was having a pint
Of Guinness in the Cosmos Bar
In Dublin
debating the fate
Of the world with his unicorn friend

Their mutual enemy, the evil fairy
Walked into the bar
And joined them in a drink

At a signal, the leprechaun
Leaped up and killed the fairy
Screaming “I must have my revenge”

The unicorn not missing a beat
Called the cops
He was not going to take the blame
For the leprechaun's crimes.
