I actually heard a SW Airlines Agent use this when I flew out of LV 5 years ago. The women ahead of me, (Couldn't recognize her with the sunglasses and hat) was making a fuss and being VERY obnoxious and finally said: "Do you know who I am?
So the SW guy got on the loudspeaker and said "Attention, please, passengers of flight 232, we have a passenger here who doesn't know who she is, can anyone help her?"
Everyone laughed. Later I found this was a standard Airline joke, but it was still funny.
