A man with a twisted grin walks into a bar, dragging a coffin behind him.
He sits at the counter and orders a whiskey.
The bartender, unnerved, asks, "What's with the coffin?"
The man replies, "Oh, it's just my pet snake's bed. He's quite big and enjoys the darkness."
The bartender, still uneasy, serves the man his whiskey.
Suddenly, the man starts laughing manically, and the coffin begins to shake violently.
The bartender, terrified, yells, "What's happening?!"
The man, barely able to catch his breath, exclaims, "Oh, my snake just realized he's been sleeping in a coffin all this time!"
