Professor Pünschge

Story

Today, again, Professor Pünschge reinvented thinking.
Full of new ideas, he leaves his “think-tank” and goes home contented. Only one way leads home, but nevertheless, Professor Pünschge goes a different way every day – according to his whim and rather personal logic.
Sometimes he wants to encounter animals.
Another time he avoids any exposure to the sun.
And there are also days on which he enters only every third space on his way home.…
Pretty eccentric, huh? No, just a little unconventional. Only those who crack the nut, which is the logic of his thinking, will be able to accompany the cunning professor.
