November 3rd is International Science Joke Day(Geo-temporally relative, of course.)
That's 6 days before Carl Sagan day.
It's a three, so that would please Tesla.
Add Einsteins birthday: 3+1+4+1+8+7+9 = 33.
OK, that last one's a stretch...
Anyway we're pretty sold on the 3rd, idea, even if those are dumb reasons.
So on November 3rd, tell a science joke to someone you love.
Or hate. Or are ambivalent about.
Hashtags are problematic. But #ISJD or #sciencejokeday are preferable.
