An engineer, a mathematician, a logician, a lawyer and an accountant apply for the position of manager of a large division. To determine who’s the most suitable applicant, the interviewer asked each of them to answer this question: “What’s 2 plus 2?”
When the interviewer asked the question to the old engineer, he immediately whipped out his slide rule and shuffled it back and forth, and finally answered, “between 3.9999 and 4.0001.”
When asked the same question, the mathematician answered “4” without missing a bit.
Next, the logician answered, “Elementary! Using deductive reasoning, I deduce that it is impossible for 2 plus 2 to be equal to 1 or 2. 2 plus 2 is also not equal to 3 since 3 minus 2 is equal to 1. So, it leaves us 4, and 4 minus 2 is equal to 2. Ergo, 2 plus 2 is equal to 4!”
Next, the lawyer answered, “In the case of Nutters v. Department of Professional Tax Hounds, the Supreme Court ruled that 2 plus 2 is equal to 5.”
Finally, when asked the same question, the accountant just smirked and asked the interviewer in a low voice, “How much do you want it to be?”
It goes without saying who got the job.
