My particular favorite is when some panicked GA pilot transmits on guard for assistance because they are having an actual emergency (like an engine failure, forced landing, are lost, etc.) and all you hear are squeals from fools stepping on each other to say GUAAAAAAAAAAAAAAAAAAAAAAAAAARD.

Yeah, people making PAs or calls to Ramp/Ops on guard are "funny" - laugh quietly to yourself and act like the damn professional you desire to be compensated as.
