Getty Images's Mark Torregrossa gives us all an explanation on the variety of snowflakes which softly float upon us, pelt us in the face and/or pile up around us. Now you can be a smarty-pants the next time it snows, which will hopefully be about a year from now.

Also, you'll find a nice compiliation of snarky comments at the end of Torregrossa's Snowflake School article. I'm sure you can top some of those.
