The Leprechaun

“Hey mister.”
I lowered my gaze and found myself staring into the green eyes of a Leprechaun.
“Do you want to buy this magic jug? It endlessly refills itself.”
He demonstrated by pouring out glass after glass of delicious red wine. I drank until I could drink no more. Incredibly, the jug was still half full... same as it had been when he’d started pouring.
“Five pounds and it’s yours,” he said.
“I don’t think so,” I slurred.
I turned and walked away. Did the daft Irishman think he was going to sell me something that was always half empty?
