He could’ve just peed instead, and then turned that into wine, right? I mean, it’s mostly water.
For that matter, so is wine …
If Jesus turns the water in wine to wine, what do you get?
Don’t be silly, Jesus didn’t pee, he was the lamb of God. Or some stupid shit.

Wonder what they would have called Data? Still ugly, of course, but he’s certainly not a bag of mostly water!
Are you sure that his bodily systems aren’t heat-sunk with water as a coolant?
Possible, although it’s never been revealed. He’s always looked very dry when opened up.
True, though any engineer capable of the delicate manufacture of a positronic brain should be a master of cable management.
I saw this comic once where Jesus could turn that water into wine, thereby effectively killing people.
