Death talking between two old pirates

Two old pirates were sitting at the local pub drinking, as they always have a “few” beers. This day, however they were feeling kind of affectionately maudlin.

"So, Alvilda, my buddy.. After I die would you pour a couple of beers over my grave? If you go first, I'll do the same for you."

Alvilda said, "Why certainly! We can do even more beers than that! But so as not to waste 'em, the only thing I’d ask is we could run ‘em through our bladders first?"
