I was remembering my father, who told the following joke:
Benny the salesman had been driving all day and now it was getting dark, so he stopped for the night at a small hotel. There didn't seem to be anyone at the hotel — the place was deserted. He went to the reception desk and a lady appeared.
"Can I help you?" she asked.
"A room please and something to eat," Benny said, "I'm dying of hunger."
She looked at him and didn't like what she saw. He was sweaty, tired-looking with bags under his red eyes and his suit was badly creased. It didn't look like he could afford a meal.
So she said, "I'm sorry, sir, but we're out of food."
Benny looked straight at her and said, "In that case, I'm going to have to do what my father did."
Immediately she grew frightened. "What did your father do?" she asked.
"My father," Benny replied, "did what he had to do."
She became even more frightened when she heard this. Who knows what kind of father this madman had? Maybe his father was a thief or a rapist, even. And she was alone with him. She decided to make him happy.
"Hold on, sir," she said and returned with a plate full of roast beef, potatoes, hot peppers and slices of rye bread.
She watched in amazement as Benny ate it all in quick time. When he had emptied his plate, he said, "That was great, the best meal I've had in weeks."
Seeing that he was now relaxed, she asked the question that had been worrying her for the last hour. "Could you please tell me what it was that your father did?"
"Oh yes, my father," said Benny. "Whenever my father couldn't get anything to eat, he went to bed hungry."
