Everyone knows smiley-face cultures irk the hell out of the Scots. It's a DNA thing.

From a review of a new-season episode of Doctor Who:

It doesn't take her [Bill, the Doctor's sidekick] long to follow his path, nonchalantly asking him why he has a Scottish accent.  

"I'm not Scottish, I'm angry," the Doctor says, before he topically japes that people from Scotland are "all over the place, demanding independence on every planet they land on."
