Holy grail

"Does anything interest you, sir?"

"I'm impressed by the make of this cup."

"Oh yes, it's a very well-made cup."

"It's large, yet I find it very easy to hold. If I may say, it's like the holy grail of cups."

"...Sir, I... I do believe the holy grail was, itself, a cup."

"What? Nonsense, it was a salver."

"A salver?"

"You know, a serving tray."

"Are you mad? The holy grail was the cup that Jesus drank from at the last supper. He couldn't drink from a tray."

"Are you suggesting that an omnipotent god who can walk on water and rise from the dead couldn't drink a bit of wine from a tray?"

"It would look silly."

"No it wouldn't."

"It would spill everywhere."

"No it wouldn't. He's a god."

"Why would he be drinking from a tray?"

"It was a miracle. No normal man could drink from a tray without spilling, but Jesus was no mere man. What would drinking from a cup prove?"

"Well, you do have a point."

"Damn right."

"So, you like the cup?"

"It's a lovely cup."
