The first guy is ordering drinks for himself and his girlfriend. The second guy, his buddy, is standing next to him.
“Whaddya havin?”, the bartender asks the first guy.
“Give me a whiskey sour and a chardonnay.”
The bartender then asks his buddy:
“Whiskey on the rocks. Two.”, his buddy replies.
The first guy, surprised at his order turns to him:
“Two whiskeys? Why are you ordering two drinks?”
The second guy answers:
“One for my demon. And one for his.”
