Looks like I'm wrong and that Jesus is real after all.

A drunken man staggers out of the pub into the path of a priest. He says to the priest in a very slurred voice, "Oi, padre, I'm Jesus Christ!"

The priests smiles and says "My son, of course you're not Jesus Christ. You're deluded, but never mind!"

"I can bloody prove it!" says yer man. "Just come in here and I'll show you!"

So they walk into the pub, and the barman looks at the drunk and exclaims "Jesus Christ, you're here again!"
