He could’ve just peed instead, and then turned that into wine, right? I mean, it’s mostly water.

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.
What a way to go though… drunk AF and a great story to tell in the afterlife about how you died. :-P
