Messing around with Mystery Google took me from a search for Bjornis to results for pants.
Here in the UK we don't mean pantalon when we say pants. They're not trousers. Someone should tell Google.co.uk this.
Okay, this isn't another example of Google putting US centric results into a Google.co.uk SERP. This is, however, an example of synonyms failing to be localised correctly and may hint at Google's current problem with getting good quality UK results.
