'Fritzchen' — Little Fritz jokes
Fritzchen, or "Little Fritz" is a fictional mischievous little boy whose name is often used in German jokes, like Little Johnny in English. Fritzchen asks his teacher, "Can I be punished for something I haven't done?" The teacher answers, "Of course not, Fritzchen, that would be very unfair!" Fritzchen is relieved: "That's good to know, because I haven't done my homework."
