Hannibal Lecter might be a funny one but somthing like this might get you in big trouble:
"An approach controller once tried to divert me. I ate his liver with some fava beans and a nice Chianti." :slurping noise"
or
"You know what you strike me as, Boston Center, with your good computers and your cheap headset? A rube, a well scrubbed, hustling rube with a little taste. Good training has given you a readable voice, but your not more than one generation from poor white trash are you, Boston Center? And that accent you've tried so desperately to shed; what did you father do? Was he a bush pilot? Did he stink of whale oil? Think, all those tedious stickly fumbling in the back seats of planes, while you could only dream of getting out...getting anywhere...getting all the way to the F...A...A...I'm going to fly away now Boston Center...fly..fly..fly away."
"Frequency change approved. I do wish I could chat longer Boston Center, but I'm having an old instructor over for lunch. Goodbye now, Boston Center."
Or to a female, "Did you breast feed your daugter, Boston Center? Cut off a man's leg and he can still feel it. When your daughter is cold and dead on the slab, where will it tickle you?"
