@schratze This reminds me of a joke:

There is a river in Germany at the Dutch border with a bridge crossing it. On the riverbed, a Dutch dude bows down and tries to drink from the river. At the same time a German crosses the bridge with his dog and sees the Dutch trying to drink from the river.

He screams off the top of his lungs: "DON'T DRINK THAT! IT'S POISONOUS! YOU CAN'T DRINK THAT!"

The Dutch guy responds: "Hm? Ik begrijp jou niet."

The German dude: "Aahhh! Je moet met beide handen drinken! Je moet met beide handen drinken!"
