What job does a pug do?

Pugs sit on sofas, preferably cuddling with their people. This is the universal job of all pugs. Some pugs watch television and my pug has taken on the responsibility of chasing horses, dogs and dinosaurs away from that magic window. Pugs alert princes to assassins and keep grandma's arthritic feet warm. Pugs teach their people to honor simple comforts and contribute greatly to an otherwise scattered and confused human dignity. And did I mention they make us laugh?
