A man walks into a bar.
"Hey barkeep, pour me up a glass of your purest madness. Make it a double."
The bartender obliges.
The man takes sip and looks around the bar, observing the different guests and the scenery.
"Ah," it says, "My brain is collapsing into reality-warping madness. It truly was an honor to be in your presence while I was sane."
