"Back in my day," began the Grandpa, and the table groaned, because they knew what was coming. "Whoever lost the last round had to sing every card they played. Still do. Go on, sing."
The loser, a serious person, stood and sang "seven of diamonds" to the tune of a hymn. "Louder," said the Grandpa. They sang a jack. They sang a nine of hearts. By the end of the round the whole table was singing along, and the Grandpa had started a story about a cow that once won a card tournament, which was not true and would be told differently next time.
The loser, hoarse, asked if they could stop.
"Not till the cow's done," said the Grandpa.
