A guy went to the same bar at the same time every day and ordered two beers. After a few weeks, the bartender said,"I don't mean to pry, but I've noticed you always have two beers. Never one and never any more. Any reason?"
The guy said,"My brother lives on the other side the country so we don't see each other very much, so we agreed to do this every day so we can have a beer together."
A few weeks later the guy ordered one beer...
"I'm sorry about your brother. This one's on me."
"Thanks, but my brother's fine. I quit drinking."
