Many thanks to all who have sent me more IHTFP information. I've had folks ask when the phrase was first coined. The earliest date I have so far at MIT is 1960, and it was well-established then. The polite form of it then was "Institute Has The Finest Professors". I've also found possible tie-ins at the US Air Force Academy (1956; their preferred alternative is "I'm Here To Fly Planes"), Lehigh University (1962; their preferred alternative is "I Have To Fart Percussively"), Renssalaer Polytechnic Institute (1963) and the US Naval Academy (1965). Does anyone know more about this now-famous acronym?

The 2013 Mystery Hunt teams had assistance from the Institute for Heist Training, Facilitation, and Planning.

The 2011 Mystery Hunt puzzles were hosted at IHaveToFindPeach.com.

The 2007 commencement saw this IHTFP drop down on five banners from Building 10.

I'll Have Thesis Finished Pronto

These made their debut as some of the graffiti on the 1994 Pei/Pay Toilet hack.

I Have To Fully Purge
I Hear The Feces Plopping

This is probably an inadvertent IHTFP:

I Hate This Fucking Planet
(Said by Lori (Sharon Stone) in Total Recall.)

The MIT library's on-line catalog has this entry for a master's thesis in EE.

IHTFP trivia: apparently at Berkeley, if you holler IHTFP out the window, everyone hollers back, "This fucking place hates you, too".

These IHTFP phrases were found on the one of the temporary first floor walls of the student center during the 1987 renovations. In the original version on the wall, in the first line, the word "Have" was crossed out, and replaced with "Hacked".
