This one was always my favorite. Doesn't really have to do with airlines much but it still makes me laugh

I'll always remember a certain radio exchange that occurred one day as Walt (my back-seater) and I were screaming across Southern California 13 miles high.
We were monitoring various radio transmissions from other aircraft > as we entered Los Angeles airspace. Though they didn't really control us, they did monitor our movement across their scope. I heard a Cessna ask for a readout of its ground speed."90 knots" Center replied.
Moments later,a Twin Beech required the same. "120 knots" Center answered.
We weren't the only ones proud of our ground speed that day...as almost instantly an F-18 smugly transmitted, "Ah, Center, Dusty 52 requests ground speed readout." There was a slight pause, then the response, "525 knots on the ground, Dusty."
Another silent pause.
As I was thinking to myself how ripe a situation this was, I heard a familiar click of a radio transmission coming from my back-seater. It was at that precise moment I realized Walt and I had become a real crew, for we were both thinking in unison.
"Center, Aspen 20, you got a ground speed readout for us?" There was a longer than normal pause ... "Aspen, I show 1,742 knots." No further inquiries were heard on that frequency.
