One morning, Mrs. Ferdinand said to her husband, "Roger, there's a meeting at Mrs. Young's house at lunch time today, and I want to go. 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?"
"This tin of fish," Mrs. Ferdinand said, "and there are some cold, boiled potatoes and some beans here, too."
"That's good," Mr. Ferdinand said. "I'll have a good lunch."
So Mrs. Ferdinand went to her meeting. All the ladies lunched at Mrs. Young's house, and at three o'clock Mrs. Ferdinand came home.
"Was your fish nice, Roger?" she asked.
"Yes, but my feet are hurting," he answered.
"Why are they hurting?" Mrs. Ferdinand asked.
"Well, the words on the tin are: 'Open tin and stand in hot water for five minutes!'"
