A professor wanted to test the IQ of his students in class, he asked a boy, "There are 10 birds sitting on a tree. You shot one. How many are left?"

The student asked, "is it a silent pistol, or other guns without sound?"

"No, it has gunshot."

"How loud is the gunshot?"

"80-100 decibels."

"That is to say, the sound of the gunshot will make your ears ache?"

"Yes."

"Is it illegal to shoot birds in this city?"

"No, it won't break the law."

"Are you sure that bird was really killed? How do you verify that?"

"Sure." Professor is impatient.

"Please, tell me how many are left, OK?"
"OK. Are there any deaf one in the birds?"
"No."
"Is there a bird with mental problems in it, which too stupid to know to fly away when it hear the gunshot?"
"No, they all have an IQ of more than 200!"
"Are there any birds kept in cages?"

"No."

"Are there any other trees by the side and any other birds on the trees?"

"No."

"How about…ten miles around?"

" There are just such a tree! "

"Are there any disabled or hungry birds that can't fly?"

"No, their health and body all in great shape."

"Do we count the birds in the pregnant belly? Can they also be counted as one?"

"They are all male."

"They can't be pregnant?"

"No... It's impossible. "

"Is the shooter dazzling? Is his eyesight good? How does he make sure 'they are ten birds'? "

"He has no dim eyesight or

blurred vision. There are only ten birds." the sweat on the Professor’s forehead is visible now.

After class, the bell rang, but the student continued to ask, "are there any birds that are too stupid to be afraid of death?"

"No. They all are afraid of death."

"Did some of them choose to stay and ready to die, because his lover was shot?"

"Fool, I said that they were all male!"

"Is homosexuality OK? How do you determine their sexual orientation? "

“... their sexual orientation is hetero! "

"Will he kill two birds with one shot?"

"No."

"kill three birds with one shot?"

"No!"

"How about four?"

"No!!"

"And five?"

"Absolutely not!!!"

...

"Will the bullet have knocked out the tree? If there were no trees, there would be no birds! "

"No. It's just an ordinary pistol which is not so powerful. "

"... Well, are all the birds free to fly? "

"Absolutely yes."

"Will they panic and bump into each other when they take off?"

"No, every bird has installed a satellite navigation system, and it can fly automatically."

"Well, your reply is not deceiving me…"

the student replied confidently, "if the dead bird is hanging on a tree & does not fall from it, there will be one left; if he falls, there will be no one left."

The professor tried to resist his feeling of fainting, & said with trembling voice

“you can become a great civil servant...".
