One tradition of the Jewish holiday Purim is to take measures to stamp out the name of Haman, the man who tried and failed to kill all Persian Jews in the Purim story. This manifests in other little traditions but one of the most literal involves people writing Haman’s name (in English or Hebrew) on the sole of their shoes so then they walk about stamping out the name throughout their day. Sometimes this is even paired with secondary events to maximize stamping such as a footrace.
While never personally observed by this folklorist (my synagogue doesn’t do this) this tradition stands out as a humorously obvious interpretation of the idea to stamp out the man’s name and ergo very believable. It’s an ancient, international holiday; someone has to have done this. The humor is assuredly intentional and adds to the joyous vibe of the rest of the holiday.
