tu risques de te faire pincer très fort (pastiche)

This is for French people only, and even, parisians only...
The picture at the top is a standard sticker in the Paris metro, explaining to children they "shouldn't put their hand on the door", as these are sliding doors, which will pinch them terribly when opening (like happens to the rabbit).
This picture is almost 50 years old; I believe anyone having lived even just a week in Paris between 1980 and now remembers it.
Now, the picture below is a very recent fake, sticked purposedly there, that says 'don't put your EYES on advertisements ('pub' in French) otherwise you'll be terribly manipulated' ;-)
I must say I guffawed...
