the dutch have a reputation for 'thriftness' that extends to cheap--there are seveal idions in english that testify to this. the most famous one being "Dutch Treat" ((there is no 'treat', you get to pay for yourself!) --variation include 'going dutch' --and Poles occupy the 'not to smart' ethnic group (they share it with blondes)--but other groups have other stereotypes.
before the 1850's or so, most police departments, (or what ever civil authority there was) had "black Marias" wagons to to round up 'ladies of the night', and other criminals.
but after the irish immigrated, these became, almost universally, "paddy wagon's" --since they were put to use picking up "paddy's (drunk irishmen)

one of my favorite set of jokes is the lightbulb series, since it gets around to insulting every ethnic group eventualy..
i know 'light bulb jokes (How many X does it take to screw in a light bulb?") that insult blondes, poles, WASP's, NYer's, jewish mothers, shrinks, programmers, Micro-soft, californians, just to name a few!
