The UK sure is in for top marks in music and comedy... but food?
Regarding the teeth - I actually never noticed it myself, but I just love that bit in Simpsons when Lisa is about to get braces and for educational purposes is shown the Big Book of British Smiles. Nothing like a good cliché.
Still, count yourself lucky! I'm in Germany, and though I'll probably always stay here - it's just home - regarding the previous categories, we've got... erm... good teeth... and rather good food. Yep, that's it.
