You know what really grinds my gears? Somebody who quotes themselves like they were a historical figure. Like, say, in the middle of a presentation, mixed in with quotes from Churchill and Roosevelt and Martin Luther King, Jr., there is a quote from the guy giving the presentation. In fucking quotes and everything, and with a citation.

"I am a pompous douchebag who thinks that their words are so profound that they need to be carried on through the generations." - I.M. Adouche

You don't need to quote yourself! You are you! The reason that quotes exist is so that you can cite somebody's point without stealing credit for their words. But since anybody who gets quoted is obviously a person of stature - how else would we know what they said, and why else would we care - putting yourself in quotes assigns that same stature to you.

At least, that's what you are trying to do. Except it doesn't work, because its such an embarrassing thing to do, that the only status that gets assigned to you is the status of being a douchebag.
