Quoting from Draw A Werewolf on Tumblr:
Tonight’s super ultra blood moon mega eclipse means you HAVE to draw a werewolf and tag it with #DrawAWerewolfDay or the moon will get really close to your house and crush it. Neil deGrasse Tyson confirmed it just now on a phone call that I did not record and will not share with you.
More info on DaWD here. Get drawing (regardless of how talented you think you are [or are not]) or that moon’ll smush you.
