Once upon a time, Joe goes to Europe. One day, he walks into a bar and orders three beers from the bartender and drinks all of them. After repeating this a few times, the bartender becomes curious and asks, "Excuse me, why do you always drink three beers at once?" Joe responds, "My brothers, Mike and Bob, and I are triplets. We're all in different parts of the world. Whenever we go to a bar, we drink a beer on behalf of the others. That's why I drink the other two beers." Then one day, Joe enters the same bar but orders only two beers. After he finishes the beers and is about to leave, the bartender asks sympathetically, "I'm sorry for your loss, did one of your brothers pass away?" Joe replies, "No, I quit drinking!"
