A horse walks into a bar.
He goes up to the bartender and orders a Martini.
The bartender mixes the drink and hands it to the horse.
The horse hands the bartender a £20 note, and the bartender gives the horse 5 Pounds in
change.
The horse stands there, sipping the drink, while the bartender wipes the counter.
After a few minutes, the bartender says, "We don't get many horses in here."
The horse replies, "At 15 quid a Martini, I'm not surprised."
