The Holy Grail or Christ's Coffee Mug?

I know it's been awhile, but I had to document this. It was released through MSN news that a ancient mug was found near Alexandria. On it, in Greek, is the inscription "Christ the Magician".

It got me thinking...

Could this be Christ's cup? The Holy Grail? or just some guy's souvenier coffee mug from a performance (What happens in Alexandria, stays in Alexandria.) of "The Great Christo!! and his assistant, the beautiful Mary M!

Makes me think...
