Scotch

A Scotsman walks into a pub and orders three double whiskies. He downs one, engages in casual conversation with the barman, eventually finishing the other two.

Next day he comes in and does the same. This goes on for a few days until the barman finally says: "You know, I can put all those doubles in a pint glass for you."

"No, no, I prefer it this way. See, I'm very close to my two brothers, but one lives in America now and the other in Australia, so this represents a drink for each of us. This way I can be closer to them and feel like we are all having a drink together."

The barman agrees and continues to set them up as requested. This goes on for several months, then one day, the Scotsman orders only two doubles. The barman begins to worry that maybe something has happened to one of his brothers. Finally, he asks: "Is everything all right?"

"What do you mean?" replies the Scotsman.

"Well", the barman says, "All these months you've ordered three drinks. Now you've only ordered two, I hope something didn’t happen to one of your brothers."

"Oh no," the Scotsman replied, "They’re both fine. It's just that I quit drinking."
