The barman says, "Wow, you must have had one hell of a day."
"Yeah, I just found out my oldest son is gay," the man says and slams down the six shots.
The next day, the same guy comes into the bar again and asks for six more vodkas, "But make them doubles!" When the bartender asks what's wrong, the man says, "I just found out that my youngest son is is also gay!" Again, he slams down the shots.
The next day, the guy is back again but this time he orders a whole bottle of vodka. The bartender says, "Jesus! Doesn't anybody in your family like pussy?"
The man downs half the bottle before saying, "Yeah, my wife!"
