LOL naaah. No sheep required for dirty deeds here. You forget the Bavarian tradition of "Fensterln" (lit. "windowing" - visiting your GF secretly at night through the window, ideally without her parents noticing it. If they do, your ability to mow the lawn might be somewhat limited for a few weeks..).
We use sheep exclusively for the lawn, as warm socks/sweaters/cardigans and as a tasty supper.
Sheep are quite popular in big cities as they are less noisy than lawn mowers so that you can have them shorten your lawn at noon, after 22:00 and on Sundays when using a motorized mower would not legally be permitted. Plus the kids love them
