Okay I'll bite... This one goes back to my flight instructing days.
I was in San Antonio for a year flying 152s and Grumman Cougars. Needless to say, when it is 112 degrees outside and you've been flying for nine hours....you aren't the sharpest knife in the drawer.
We're on final for the right side with a 737 hauling up our arse. I told the controller we could sidestep to the other side if it would help.
"I *SAID* 'CLEARED TO LAND, NINER *RIGHT*!'" the controller replied.
"Roger, cleared to land niner right, Cessna 12345."
I then proceeded to mutter to my student, "Gawd a m n what an a$$hole. I don't know what crawled up his a$$ and died, I was only trying to be helpful. Sheesh." *pause* "He didn't have to be such a d*ck about it." Long silence during which time I begin to suspect a stuck mike. I tried to gracefully exit. "Well...actually, he's just trying to do his job. He's not the d*ckhead, I am." *Click* (Sound of me unsticking mike.)
"Cessna 12345, you guys need to pay attention to your equipment. You've had a stuck mike for about thirty seconds."
WOOPS...............
Before switching to ground I managed to say, "Great job sir, previous comments notwithstanding."
D'OH! What a lunkhead.
