A man walks into a bar and orders three mugs of beer.
The bartender tells him they will go flat while he drinks.
But the man explains to him, “I have two brothers. When we all left home we decided every night we will all go to the bar and have a drink for each of us.”
This man becomes a regular and orders three beers every night.
But a few months later he comes in silently and orders only two.
The bar falls silent.
The bartender approaches him and says, “I don’t mean to intrude, but I’m sorry for your loss.”
The man looks puzzled at first then laughs, “Oh, no! It’s just that my doctor said I had to quit drinking.”
