"I grant ye, the Eyetalians ARE some given to jabbin' knives into each other, but they never git up strikes, an' they don't grumble about wages. Why, look at the way they live--jest some weeds an' yarbs dug up on the roadside, an' stewed in a kettle with a piece o' fat the size o' your finger, an' a loaf o' bread, an' they're happy as a king."
- Harold Frederic, The Damnation of Theron Ware, ch. 3
It's hilarious! It has some scenes of over-the-top violence, ridiculous to the point of just adding to the humor, but if you're squeamish you might want to avoid it. Otherwise, it's highly recommended. ;-)
If I recall correctly, one of the characters in the movie Hot Fuzz only has one word in his vocabulary: yarb, pronounced the way I described. Maybe that's where I get the image. He wasn't a pirate, though.
