This reminds me of a joke, some variation of which has been circulating for a long time. Here's the first version I could find easily:
An assemblage of the most gifted minds in the world were all posed the following question: "What is 2 x 2 ?" The engineer whips out his slide rule and shuffles it back and forth, and finally announces "3.99". The physicist consults his technical references, sets up the problem on his computer, and announces "it lies between 3.98 and 4.02." The mathematician cogitates for a while, oblivious to the rest of the world, then announces: "I don't what the answer is, but I can tell you, an answer exists!" The philosopher says, "But what do you mean by 2 x 2 ?" The logician says, "Please define 2 x 2 more precisely." The accountant closes all the doors and windows, looks around carefully, then asks "What do you want the answer to be?"
