ozstamps, this is just some nationals insider talk, which I believe every nation has. Some countrymen are conbsidered to be "stupid" (in Germany: Ostfriesen), some "humuorous" (G.: Rheinländer), some "dull" (G.: Westfalen), some ".....rdly" (G.: Schwaben)
.... and the Swiss are considered "mentally slow" here. See, as we all know by example, this is just a klischee.
