A farmer just got married and was going home on his wagon pulled by a team of horses.

When one of the hoses stumbled, he said, “That’s once.”

Then it stumbled again. He said, “That’s twice.”

Then later it stumbled a third time.

This time, he didn’t say anything, just pulled out a shotgun and shot the horses dead.

His wife cried out and started to yell at him.

The farmer turned to her and said, “That’s once.”
