Nedavno jsem videl film Sweeney Todd, ktery mi pripomel jednu hezkou hadanku. Napisu jeji zneni v anglictine, nebot do cestiny se to preklada dost krkolomne.

There is a village where all man are obligated to be shaved. There is only one barber in the village thus every man either shaves himself or goes to the barber. This implies that barber shaves all those who don't shave themselves. The question is: is the barber man or woman?

Zkuste tuto hadanku vyresit. Zajimalo by mne, zda se to povede tem, kteri nevi co je to Russeluv paradox. Ti, kdo to vi, samozrejme reseni vedeli jeste driv, nez stacili docist do konce, cili ti necht zkusi dat prostor tem, kteri nejsou v tomto smeru jeste tolik vzdelani.
