One day, Mrs Perry said to her husband, "Jack, I'm going to meet some ladies at Mrs Young's house for lunch today. I'll leave you some food for your lunch. Is that all right?"
"Oh, yes," her husband answered. "That's quite all right. What are you going to leave for my lunch?"
"A tin of fish," Mrs Perry said, "and there are some boiled potatoes and beans, too."
"Good," Mr Perry answered, "I'll have a good lunch."
Mrs Perry went to her meeting. All of the ladies had lunch at Mrs Young's house and at 3:15 pm she came home.
"Was your fish nice, Jack?" she asked.
"Yes, but my feet are hurting," he answered.
"Why are they hurting?"
"Well, the instructions on the tin said 'open tin and stand in hot water for five minutes'."
