An ignorant husband

One morning Mrs.Perry said to her husbad, "Jack there's a meeting of our ladies' club at Mrs Young's house at lunch time today, and I want to go to it. 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 Perry said. "And there are some cold, boiled potatos and some beans here, too".

"Good", Mr Perry answered. "I'll have a good lunch".

So Mrs Perry went to her meeting. All the ladies had lunch at Mrs Young's house, and at three o'clock Mrs Perry came home

"Was your fish nice, Jack?", she asked.

"Yes, but my feet are hurting" he answered.

"Why are the hurting?", Mrs Perry asked.

"Well, the words on the tin were, "Open tin and stand in hot water for five minutes""
