"Reason To Drink" joke

A guy walks into a bar and orders 12 tequilas. The bartender
asks, "What's wrong."
The guy says that he just found out that his younger son
is gay. The bartender
says, "I'm sorry about that buddy."
After a couple of days the guy comes back and orders 15
tequilas. The bartender
enquires, "What's wrong now?" To
which the guy responds that he found out
that his older
son was gay, too. The bartender says that he's sorry.
The guy returned a few days later and ordered 20 tequilas.
The bartender
burst out, "Isn't anyone in your family
gettin' any pussy?!" and the guy
looks up and sneers,
"Yeah, my wife!"
