How can you tell an extroverted engineer?
He stares at your feet while he's talking to you.
A social worker, a priest and an engineer were out golfing one day when they saw a group of men randomly hitting balls all over the course. The social worker asked the range officer about it, and the range officer said, "Those men are fire-fighters, and they rescued the owner of this golf course and his family from a burning building, but in the process, they were all blinded. He let's them play for free as often as they want." The social worker said, "I'm going to recommend them for a heroism award." The priest said, "I'm going to pray for them tonight." The engineer said, "Why can't these guys play at night?"
An engineer, a writer and an economist were all discussing whether it was better to have a wife or a mistress. The writer said, "Having a mistress is exciting and sexy, so that's clearly better." The economist said, "Given the tax breaks for married couples, and the relatively low cost of a wife, it's better to have that." The engineer said, "It's better to have both." "Both?" The writer and economist asked. "Yes, both. You see, when you're gone, the wife thinks you're with the mistress, and your mistress thinks you're with your wife, and you can go to the lab and finally get some work done."
Once, a farmer was having trouble with his chickens. They weren't laying any eggs, so he asked a biologist, a biochemist and a physicist to come out and solve the problem. The biologist took a random sample of 30 different chickens from different farms and determined their weight, feather density, number of toes and eye color. She then applied a variety of multivariate statistical algorithms that she didn't fully understand, and then wrote 4 papers with contradictory conclusions. Due to robust sampling methods, none of the chickens from the farm in question were included in the study, although chickens from 2 neighboring farms were included.
Then the biochemist went to work. She did a full DNA workup of all the chickens on the farm, and then split them up into 16 groups of similar weight and feather color. In a simultaneous trial, she tested 4 different drugs with completely unknown pharmacokenetics and determined that the placebo effect was stronger than any of the drugs, although none of the chickens were laying eggs. She then asked the farmer to triple the budget so she could test a larger group of chickens and account for the apparent variation in toenail color.
The physicist then spent 20 minutes looking at one of the chickens. She scurried off with her notebook and a pen and spent 2 hours furiously writing down equations. When she finished, she went over to the farmer and said, "I've done it! I solved it! But it only works for a spherical chicken in a vacuum."
