I posted the following tale in a thread on a ranging Amigoville discussion of immigration and attitudes ...
" Back in '74 I was driving back from a fishing weekend at Besnard Lake northwest of Lac La Ronge in Saskatchewan with three friends ... a French-Canadian hardware salesman, a 3rd generation immigrant Polish design technologist, and a 1st generation Dutch architect. The latter two were in the back with a case of beer which they had visited several times.
My Dutch colleague at some point began referring to our francophone friend as 'frog' solely because he knew it annoyed him. While the car was stopped so the the two in the back could relieve themselves of some of the beer pressure, my companion asked me if I knew how to stop this 'frog' business. I suggested that the the next time the Dutchman referred to him as 'frog' he should call him a kraut.
We were on the road again shortly and the 'f' word was used again. Marcel calmly responded "Knock it off you f_____g kraut" Silence. Then about a mile further down the road beer cascaded over my head and a voice from the back said "He never thought of that by himself".
