Three Irish brothers always get a pint together after work.
Eventually, two of them moved away, and one brother who stayed would order three pints so it would feel like any other night at the pub with his brothers.
One day he comes to pub and orders only two pints.
The pub falls silent and the barkeep says they are on the house and offers his condolences.
The barkeep then asks which brother had died and the guy says his brothers are both healthy.
“But you only ordered 2 pints” to which he replied “oh, I quit drinking!”
