Wizard of Id

"Oh, man," says Bung to the bartender, "last night's Halloween party was brutal... just give me a water."
"Ugh..." says a child, "water for me, too..."
"Wait, kid!" says Bung. "You didn't..."
"I must have had twenty Kit Kats" says the child.

Meanwhile, the bartender has served them each a glass of some suspicious yellow liquid in which ice does not float.
