Or how about something an Australian pilot wished he hadn't said.
Flying Mirage IIIs on detachment to some exotic Indonesian/Malaysian type locale the "lads" had downed large bowls of street vendor curry and beer the day before a session of 1v1 BFM.
The pilot feels a little "gurgle" as he enters the cockpit but thinks nothing of it and concentrates on the mission at hand - the Mirages enter a fast head-on merge at altitude and our boy calls out "ok 2, fight's on !!" on the RT and cranks the Mirage into a nice 5g turn, this triggers the bladder pouch of his anti G to inflate and a good couple of pints of very watery, odious diarrhea promptly squirts down the (unsealed) legs of his flight suit and into the cockpit.
Apparently his next transmission was "knock it off, knock it off, oh Jesus Christ knock it off !!!".
