Laugh out loud

I don't think we get to laugh heartily, quite often, after college days. Here are some jokes to see if it could help us.

Chair Philosophy
An eccentric philosophy professor gave a one question final exam after a semester dealing with a broad array of topics. The class was already seated and ready to go when the professor picked up his chair, plopped it on his desk and wrote on the board: "Using everything we have learned this semester, prove that this chair does not exist."
Fingers flew, erasers erased, notebooks were filled in furious fashion. Some students wrote over 30 pages in one hour attempting to refute the existence of the chair. One member of the class however, was up and finished in less than a minute.
Weeks later when the grades were posted, the rest of the group wondered how he could have gotten an A when he had barely written anything at all. His answer consisted of two words: "What chair?"

Fasten Seat Belts
Flying to Los Angeles from San Francisco the other day, a passenger noticed that the "Fasten Seat Belts" sign was kept lit during the whole journey although the flight was a particularly smooth one.
Just before landing, he asked the stewardess about it.
"Well," she explained, "up front there are 17 University of California girls going to Los Angeles for the weekend.
"In back, there are 25 Coast Guard enlistees. What would you do?"

Mom... Send Money
A college student called his mother and asked her for some money.
His mother said that she would send him money and mentioned that he had left his calculus book when when he visited two weeks ago and asked if she should send it too.
"Uhh, oh yeah, o.k." Responded the student.
Mom wrapped the book along with the checks up in a package, kissed Dad goodbye, and went to the post office to mail the money and the book.
When she got back, Dad asked, "How much did you give the boy this time?
Mom replied, "I wrote 2 checks, one for $20, and the other for $1000."
"That's $1020!" yelled Dad. "Are you crazy?"
"Don't worry honey," Mom said, as she continued, "I taped the $20 check to the cover of his book, but I put the $1000 one somewhere between the pages in chapter 19!"
