43
The 'Mystical Number of Coincidence' as first prophesied in the unforgettable 1987 Powell Peralta production "The Search for Animal Chin".

A number that shows up in the least expected places with commonly occurring frequency.

One more than 42
For some fucking reason, GAP stores like to sell shitty hats with the number 43 on them.

What do you get when you mupltiply 6 by 7 (and then add one)?
