->'''Dilbert:''' Wally, would you like to be on my TTP project?\\
'''Wally:''' What does "TTP" stand for?\\
'''Dilbert:''' It's short for '''T'''he '''T'''TP '''P'''roject. I named it myself.
-->-- ''ComicStrip/{{Dilbert}}'', May 18, 1994

An acronym in which one of the letters inside the acronym stands for the acronym itself. Because of the way English phrases such things, attempting to fully expand the acronym causes an infinite recursive loop.

Extraordinarily overused in computing culture for their giggle value, but absolutely straight-faced serious examples can be found in the business world and elsewhere.

Yes, we know you don't spell "emissions" like that, but it's written on all the stickers on the car windows... and the final S has to come from System, or Rattigan's whining makes no sense. Considering what the device is supposed to do (disregarding the Sontarans' plans), "Omissions" does make sense, as it does omit the emissions on the vehicle the device is installed on.
