A few years ago a BA 757 is taxying out at ABZ to head off to LHR. Male Capt and a Female F/O who was doing the R/T.
ATC: Speedbird XXX, your clearance?
BA 757: Standby (The transmission was rather garbled, since the F/O was eating some peanuts!)
Then after a short pause the F/O asks for the clearance.
BA 757: Speedbird XXX, go ahead with the clearance.... Sorry about that I had the Captain's Nuts in my mouth!
