Many years ago at Arlanda when we were sat at the hold, a UK airline landed HARD in front of us, and bounced before landing again. The aircraft taxied off the runway, and shortly afterwards we heard a rustling noise on the radio, followed by "you f***ing clown" in a hysterical tone, more rustling noises were heard, followed by "oops" and the transmission clicked off. A few moments later, the same voice was heard talking in a very calm manner to ATC, as if nothing had happened.
