This comes from a search and rescue pilot at Canadian Forces Base in Bagotville, Quebec. It happened late one night during bad weather, as heard over the tower radio:
Helicopter pilot: Roger, I'm holding at 3,000 feet over the beacon.
Second voice: (Panic in voice) No, you can't be doing that...I'm holding at 3,000 feet over that beacon.
Helicopter pilot: (Short pause) You idiot, you're my copilot.
