One of the "old dogs" was apparantly somewhat pre-occupied once working the radar:
ATC: Elite001, fly heading 310, sir, and report new heading... sir.
-a looooong pause...
A/C: Uuh, Elite001 now heading 310.
We were rolling on the floor laughing, poor pilots, they must have been going: "it´s a trick question, you answer it. NO! YOU answer it..."
