Student Naval Aviator (SNA) flying in back on an instrument hop, very lost, very flustered, inadvertently keys XMIT instead of ICS to tell Instructor Pilot (IP) he is less-than-optimally situationally aware:

SNA: (broadcasts to world) "Sir, I'm all fucked up."
Whiting TWR: "Aircraft using obscenity, identify yourself."
(short pause)
IP: "My student said he was fucked up; he didn't say he was stupid."
