The Hairy Twats Bikers had me thinking on their recent Sweden episode. They were pronouncing 'Same' as 'Sammy', not 'Sarmey' as I learned in Sweden. The locals were pronouncing it back at them the same way. Now I don't know if the Same were just being polite or if really is 'Sammy' and I've learned the Swedish version which is wrong to Same ears.
The HBs did also mangle the local place names, so I'd think it was more likely to be them.
