Van Nuys airport CA, 1994 doing my PPL, while taxiing back to the flying school in a C150 about 10 hours into the training:
Ground Controller "November XXXX taxi back to flying school"
Me "Roger XXX" and off I go across a taxiway intersection without looking as carefully as my (very vocal and occasionally physically violent but good guy nonetheless Italian instructor would have liked).
Instructor to me "FuX%ing look before you cross a taxiway - these controllers don't give a !!!! about us pilots, they're all dopey bastards anyway, what are you going to say to the NTSB when your aircraft is cut in half by someone else's propeller because you didn't look properly and believed those effing liars in the tower? etc..."
5 mins after shutdown the school took a call - we had had a stuck mike. They had heard everything - cue visit to ATC and large serving of humble pie. Still makes me smile.
