The Last Ship (2014)
keelhauling
from the episode "We'll Get There"
XO Mike Slattery: "You ever hear of keelhauling?"
Quincy Tophet: "Can't say that I have, no."
XO Mike Slattery: "Really? See, back in the mid 1800's, if a sea captain encountered a particularly problematic sailor, he'd have him bound with rope, thrown over the side of the ship, dragged underneath the hull. Poor bastard would bounce and scrape along the keel, barnacles and such. And when he'd come up on the other side, if he wasn't drowned or decapitated, he tended to be a lot more cooperative."
