One day when I was a junior medical student, a very important Boston surgeon visited the school and delivered a great treatise on a large number of patients who had undergone successful operations for vascular reconstruction.
At the end of the lecture, a young student at the back of the room timidly asked, "Do you have any control subjects?"
The surgeon drew himself up to his full height, slammed the desk with his fist, and said, "Do you mean did I NOT operate on half the patients?!"
The hall grew very quiet then. The voice at the back of the room hesitantly replied, "Yes, that's what I had in mind."
Then the surgeon's fist really came crashing down as he thundered, "Of course not!! That would have doomed half of them to their death!!"
God it was quiet then.... And one could scarcely hear the small voice ask:
The reason why bowling alleys are so quiet is such that you can hear a pin drop.
Why should a bowling alley be quiet? So you can hear a pin drop!
What Mother Superior Found
The mother superior is very upset. She walks into the dinner room and announces to all the nuns to be quiet and listen.
"I was walking around the gardens, as I do." She says in a loud voice, "When I found some disturbing things! For one, I found a man's underpants!"
All the nuns are taken aback except for one, who is smiling.
"Then, " continues the mother superior, "I found a WOMAN'S underpants!"
All the nuns gasp together, except for one, who is giggling.
"And if that wasn't enough, I found.... a... a... used condom!"
All the nuns gasp, and some turn white, except for one, who is laughing quietly.
"And in the condom," finishes mother superior, "was a hole."
All the nuns laugh, except for one, who is crying.
