Exam joke

[shillelagh]

There was a father and son who were always in competition with each other. One day the son left to take an entrance exam at a university. He wanted to major in medicine. A week later he returned from his trip looking very down in the dumps.
"How was the exam?" asked his father.
"They asked quite a lot of 'Fill in the missing letter' questions about first aid and stuff. I got a score of 75%. It wasn't good enough to get accepted," the boy replied.
"Well in that case I better take that exam myself," the father said. So off to the university he went. A week later the father returned from his trip looking very down in the dumps.
"How was the exam?" asked his son.
"They asked quite a lot of 'fill in the missing letter' questions about first aid and I got them all wrong but one."
"Gee, Dad. Which question was that?"
"The question was...", started the father, "What do you do when you come across a lady which has fainted. You feel her PU_S_ ?"
"That's easy", the son replied. "The answer is pulse."
"Oh, hell," said the father," I got that one wrong as well."
