Title character of a series of
cartoons entitled "The World of Commander McBragg". The Commander (a retired Naval officer) is a stereotypical upper-class
British blowhard who forever sits in his library telling
wild and highly
improbable stories about his many
adventures. All of these stories end with him saving the day by some amazing feat of strength or cleverness. At the end of each
tale his unnamed listener (a white-haired crony of the Commander's) would make a terrible
pun, to which the Commander would respond with a dry "Quite."
The cartoons originally appeared on the Tennessee Tuxedo show, and then on Underdog. I meself have only seen them via the Rocky and Bullwinkle show.
"Good HEAvens, Commander -- what EVER did you do?"
