What do you do on Mad Hatter Day?

Mad Hatter Day is an informal, unofficial holiday that celebrates the Mad Hatter character from "Alice in Wonderland"; on this day, those who mark the holiday act in a lightheartedly unhinged manner similar to the Mad Hatter. This holiday falls on October 6 each year.

This date is designated for the celebration of Mad Hatter Day as a reference to the slip of paper the Mad Hatter keeps in his hat. This paper reads 10/6. As October is the 10th month, the sixth day of this month corresponds to the numbers written on that paper. Revelers may not want to go so far as to recreate the mercury poisoning that likely inspired the Mad Hatter's zaniness.
