Claire Bretécher died at the age of 79

She was a trailblazing comic strip artist with an incredibly explicit page in the Nouvelle Observateur during the '70 and '80 of the last century.

Here's a harmlesser, yet informative drawing from that period:

Do you get it? Don't be shy. (Hint: this joke wouldn't work today (Heidegger was a celebrated German philosopher, who would routinely write lines such as: "Das Sein seint, und das Nichts nichtset" (which don't even make sense in German (J.-P. Sartre visited Germany during the '30's to meet Heidegger and hailed him as the leading inspiration of his own Existentialism (Hanna Arendt was Heidegger's girlfriend before she fled the Nazis and went to America))))). 

(Yes, yours truly did a lot of LISP programming (don't ask)).

Let's get serious: 40 years ago, intellectualism (like dropping names of philosophers) still did things to people; now we have Donald Trump (not Trump's fault (Trump is a symptom, not a cause (as we have been saying long before Obama did))). 

(In this spirit).
