For whatever reason, there are a couple of commercial campaigns right now which really play up the Scottish stereotype. First there's that motor oil one with a guy with a bad Scottish accent running around smacking people with a dip-stick and calling them all "Jimmy." I've never known any Scotsman to go around calling everyone "Jimmy."
And now there's one for a candy implying that it's a contradiction for the characters to be Scottish-Korean. Is that really any stranger than being Hawai'ian/Norwegian on one side and Scot on the other?
Is there some reason that the Scots are currently the fashionable ones to make fun of?
