Doesn't the "L" of the "KLOTZ" neon sign also flicker at some point, strongly evoking the connotation "KOTZ" ("PUKE"), just as Evelyn Hamann feels slightly overwhelmed after tasting too many Klotz-Riegel?

I just love how Loriot managed to combine immature puns and insinuations and profound character studies into surreal pieces of art that cause whole families to laugh until one cries. May he rest in peace.

Never noticed (or never committed to memory after noticing), but yeah, how could that opportunity be left untapped. He was a perfectionist engineer of jokes, the entertainer equivalent to that proverbial Scala coder who'd rewrite the entire thing if he came up late with an idea to monadify away yet another side effect. May he rest in peace, and may upcoming generations memorize that movie just like we did (it was already twenty years old when I started falling for it)

Wow, I got this wrong for at least ten years.

And I got Riegel Klotz wrong, for a similar time: thought that it was Riegel Drögel, when it's in fact Riegel Klotz and Riegel Drögel only appears in a few lines. Only corrected myself through Google-checking my writing here.
