“I have keen eyes. I once caught a leprechaun you know."
I looked at him skeptically. "Aren't those Irish?"
"Sure. He was over in the homeland on an exchange basis. We sent the Irish three turnips and a sheep's bladder in trade."
"Doesn't seem like much of a trade."
"Oh, I think it was a sparking good one, seeing as to leprechauns are imaginary and all. Hello, Prof. How's your kilt?"
"As imaginary as your leprechaun”
