The Letter R

Time for another German lesson!
On the left I´ve illustrated the German saying "Roß und Reiter" which means to name names, to point out who is responsible for something gone wrong.
"Rabenschwarz" means black like a raven or jet-black, but in German it´s possible to say that in just one word. It´s often used to characterize someone´s black humour.
And on the right you can see a life buoy or life saver which is "Rettungsring" in German. This word is often used for overweight. Well, the guy on my ATC has them both ;-)
