Smash up graham crackers, cinnamon & sugar together.
Get the rim wet and dip it into your cinnamon, sugar and cracker mix. 
PROTIP: Use maple syrup on the glass and you'll get extra flavor and sticking power.
Combine everything else into your cocktail shaker.
Shake like a bandit.
Pour & strain into your magnifinently rimmed martini glass. Garnish with a little bit of grated nutmeg (fresh, naturally). 
Enjoy the power of the pumpkin pie anytime you'd like, not just at Thanksgiving.
