I heard this from my brother, who is a Search and Rescue pilot at Canadian
Forces Base Bagotville, Quebec. Its an apocryphal story that allegedly
happened late one night during bad weather, as heard over the tower radio:

Helicopter Pilot: Roger, Im holding at 3000 over <such-and-such> beacon.

Second voice: NO! You cant be doing that! Im holding at 3000 over
that beacon!

(brief pause, then first voice again): You idiot, youre my co-pilot.
