Script

Steht ein Rasenmäher auf der Wiese. Da kommt ein Schaaf vorbei und sagt Mäh.
Der Rasenmäher antwortet: Du hast mir hier gar nichts zu sagen.

Explain

This is a joke for advanced german learners. Can you guess it?

To understand you need to know what parents her children teach when they explain different animails. For example a dog makes: Wau, a cow makes: Muh and a sheep makes: Mäh.

This sounds very close to the second part of the germen word vor lawnmower Rasen-Mäh-er.

In this case the lawnmower recognize this Mäh sound as a command that he know should start to work. Like in the german sentence: Mäh du den Rasen.
