My winner is
Surplus's slightly cruel
"For the last time, I've not put on weight and I'm not Adam Sandler."
Honorable mention to Racedo's
"Hey Ginger, do you know Biggles and Algy?"
and Coff...'s jolly-good
"Well Sir ... Bags of initiative shown there ... Our red occulting anti-collision light had failed and quick as a flash you whipped off the jolly old bonedome and you stuck your head out the side window ... Outstanding airmanship"
