Finally heard a great comeback to all the '121.5 Nazis' today....went like this:
Perpetrator, on guard: Center, *blah**blah*blah*
Guardian of Guard 1: "On Guard"
1 millisecond later
Guardian of Guard 2: "You're on guard!"
*pause*
Perpetrator, on guard: "So are you!!!"
All this in the midst of half the country searching for a National Guard chopper that didn't close his flight plan....
Cheers to that guy, what a great comeback
