You will probably wonder just as much as I did who this gentlemen is. Walking through Schaerbeek, and by complete chance, I came across Nasreddin Hoca.
And after some research I also figured out who Nasreddin Hoca is. A satirical sufi, a wise man found in the Near and Middle East in the Middle Ages. His actions and stories are illogical yet logical, rational yet irrational, bizarre yet normal. Sort of a satirical stand up comedian in modern day terms.
