Rainbows and Butterflies

Auf Deutsch: Regenbogen und Schmetterlinge. Regenbogen, okay. I'll accept that one as Regen is rain and Bogen is arch (or bow). So that sort of makes sense. But Schmetterling??? It sounds like something you scrape off the bottom of your shoe after using the public bathroom in the train station. I know. I know. Rainbows and butterflies are beautiful in any language and in any country. Still, let's just enjoy them silently, shall we?

 p.s. Yes, it is STILL raining in Munich.
