An American walks into an Irish pub, he asks the bartender for an Irish Car Bomb.
The bartender grimaces, "Excuse me?"
The man smiles, "It's a drink, you don't have those? Irish car bombs?"
The bartender lights up and replies, "Oh I have something similar, one moment!"
He then takes two tall shot glasses side by side, fills them with vodka, and lights them aflame.
"Special, just for you."
The American frowns, "What the hell is this?"
"I call it a 9/11."
