"By Joe Butt"

I lol'd a LOT harder than I should have...

I'm, based on this test, INTP. Half of the questions were "wtp is it asking...?" or "How would i know?", so I won't rely on it too heavily.

Edit:

Precise about their descriptions, INTPs will often correct others (or be sorely tempted to) if the shade of meaning is a bit off. While annoying to the less concise, this fine discrimination ability gives INTPs so inclined a natural advantage as, for example, grammarians and linguists.

Mr Butt here just called me an OCD Grammar Nazi, didn't he....
