Very useful for the introduction by Winfried Ulrich, the nich only the questions of what actually is a joke and what the dt. From English. Witz differs, pursues. It also explains very clearly the 5 categories, in which the "jokes and puns" are arranged:
-Fehleinschätzungen
-Missverständnisse
-Anspielungen
-Selbstenthüllungen
-Übertreibungen
All in all, a book that is interesting not only because of the laughs, but mainly because of the clarification of cultural differences.
