INTP: The Egghead
The typical INTP is a logical, abstract thinker whose intellect is ideally suited to understanding pure mathematics, linguistics, formal logic theory, and other pursuits unsuited to making a real living. The INTP can often understand even the most subtle nuances of lattice quantum chromodynamics, but cannot perform more concrete tasks such as dressing himself, operating a motor vehicle, or opening a door. An INTP may be able to tell you how to construct a nuclear reactor from a coconut and two pieces of string, but may be completely incapable of fixing a hole in a boat.
The INTP is really only suited to two careers: college professor and game show contestant. Of these career choices, only one offers the financial rewards which allows him to suport himself; for that reason, INTPs often take the other path, and become tenured academics.
RECREATION: Surprisingly, INTPs are often the hit of the party--not for their sometimes annoying habit of turning every discussion into a debate about semantics nor for their fascinating stories about Pierre de Fermat's habit of writing things in the margins of his books, but for the fact that they often show up with their pants on backwards and that if you put a Post-It note reading "Kick Me" on an INTP's back, he won't notice it no matter how many people kick him. That kind of entertainment never gets old.
COMPATIBILITY: INTPs make ideal companions to INTJs, as neither of them notices they're in a relationship.
Famous INTPs include Pierre de Fermat and almost everyone who knows what Pierre de Fermat wrote in the margins of his book.
