Three men: a project manager, a software engineer, and a hardware engineer are helping out on a project. About midweek they decide to walk up and down the beach during their lunch hour. Halfway up the beach, they stumbled upon a lamp. As they rub the lamp a genie appears and says "Normally I would grant you three wishes, but since there are three of you, I will grant you each one wish."
The hardware engineer went first. "I would like to spend the rest of my life living in a huge house in St. Thomas with no money worries." The genie granted him his wish and sent him on off to St. Thomas.

The software engineer went next. "I would like to spend the rest of my life living on a huge yacht cruising the Mediterranean with no money worries." The genie granted him his wish and sent him off to the Mediterranean.

Last, but not least, it was the project manager's turn. "And what would your wish be?" asked the genie.

"I want them both back after lunch" replied the project manager.

An architect, an artist and an engineer were discussing whether it was better to spend time with the wife or a mistress. The architect said he enjoyed time with his wife, building a solid foundation for an enduring relationship. The artist said he enjoyed time with his mistress, because of the passion and mystery he found there. The engineer said, "I like both." "Both?" Engineer: "Yeah. If you have a wife and a mistress, they will each assume you are spending time with the other woman, and you can go to the lab and get some work done."

An engineer, a mathmatician and an arts graduate were given the task of finding the height of a church steeple (the first to get the correct solution wins a $1000).
The engineer tried to remember things about differential pressures, but resorted to climbing the steeple and lowering a string on a plumb bob until it touched the ground and then climbed down and measured the length of the string.

The Mathematician layed out a reference line, measured the angle to the top of the steeple from both ends and worked out the height by trigonometry.

However, the arts graduate won the prize. He bought the vicar a beer in the local pub and he told him how high the church steeple was.



Surgery;
Five surgeons were taking a coffee break and were discussing their work. The first said, "I think accountants are the easiest to operate on. You open them up and everything inside is numbered."
The second said, "I think librarians are the easiest to operate on. You open them up and everything inside is in alphabetical order."
The third said, "I like to operate on electricians. You open them up and everything inside is color-coded."
The fourth one said, "I like to operate on lawyers. They're heartless, spineless, gutless, and their heads and their butts are interchangeable."
Fifth surgeon said, "I like Engineers...they always understand when you have a few parts left over at the end..."


The graduate with a Science degree asks, "Why does it work?"
The graduate with an Engineering degree asks, "How does it work?"
The graduate with an Accounting degree asks, "How much will it cost?"
The graduate with a Liberal Arts degree asks, "Do you want fries with that?"
