I once listened on Guard to a single-engine ditching in progress in the Bahamas where a United pilot was trying to fix his position for the Coast Guard and advise him on ditching preparations so he wouldn't forget as he nursed a failing engine along.
Every time there was a break in the transmissions, some idiot or another would start screaming, "Guard!"
The Guard Nazis need to get their heads out of their arses.
The next time 121.5 is filled with juvenile chatter, I'm going to advise ATC that we are no longer monitoring due to frequency congestion.
