Bestimmt kennen einige hier die Kartoffelaufgabe im Wandel der Zeit. Hier mal etwas ähnliches aus den USA:

Teaching maths in 1950:
A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price. What is his profit?

Teaching maths in 1960:
A logger sells a truckload of lumber for $100. His cost of production is 4/5 of the price, or $80. What is his profit?

Teaching maths in 1970:
A logger exchanges a set "L" of lumber for a set "M" of money. The cardinality of set "M" is 100. Each element is worth
one dollar. Make 100 dots representing the elements of the set "M." The set "C," the cost of production contains 20 fewer points than set "M." Represent the set "C" as subset of set "M" and answer the following question: What is the cardinality of the set "P" of profits?

Teaching maths in 1980:
A logger sells a truckload of lumber for $100. His cost of production is $80 and his profit is $20. Your assignment: Underline the number 20.

Teaching maths in 1990:

Andre, sei doch nicht so empfindlich . Wo ist denn hier ein kritischer Beitrag? Der Witz ist doch wirklich uralt (aber trotzdem nicht schlecht ).

Und "stänkernde" Gäste gibt es doch in jedem Forum. Finde nicht, dass es hier besonders Überhand nimmt.
