3 days at bar

A guy came into a bar one day and said to the bartender, “Give me six double vodka.”
The barman says, “Wow! you must have had very bad day.”
“Yes, I’ve just found out my older brother is gay.”

The next day the same guy came into the bar and asked for the same drinks.
When the bartender asked what the problem was today the answer came back, “I’ve just found out that my younger brother is gay too!”

The bartender said, “What the hell? Doesn’t anybody in your family like women?”

“Yes, my wife…”
