When my employer (Salzburg Research) called for participation in a course about presentation techniques in English, registered people like me were asked to prepare a short presentation on „an arbitrary topic“. Undecided which topic to choose I went for the proverbial most ridiculous stuff I could find: the „love life of the cockchafers“ (also known as „May bugs“ – in German „Maikäfer“). Don’t take this too serious 😉
