This comes from a search-and-rescue pilot at Canadian Forces Base, Bagotville, Québec. It allegedly happened late one night during bad weather, as heard over the tower radio:
First Voice(helicopter pilot):
"Roger, I'm holding at 3,000 over the beacon."
Second Voice(panicky):
"No, you can't be doing that I'm holding at 3,000 over that beacon!"
[Brief pause.]
First Voice(again):
"You idiot you're my co-pilot."
