i would tell them as a small child for why we celebrate christmas....
The real Saint Nick was a marijuana entrepenour. One night he got soooo high
that we took all of his weed bricks, bagged em up into a big red sack, put on a goofy hat, whipped his midget named elf to help him carry the weed, hopped on his raindeer, and in a stoned rampage we climbed up from roof to roof dropping bricks of weed down peoples chimneys.
the end here take a hit of this..."night"
