The Unholy Grail

Okay, so you know about King Arthur and The Holy Grail, right?
It was the vessel from which Christ drank, and any who drink from it are healed of all disease and illness.
Well, I know about the Unholy Grail, from which those who drink are poisoned and suffer greatly.
Still, no matter how many times you warn the guys, the moment she spreads her legs, they all come with their tongues waggling and licking.
Then, they come crawling to me, begging for a sip from the Holy Grail.
“It’s in the dishwasher,” I say, and I slam the door.
