21 Friday the 13th tweets to read before Jason kills you.

It's Friday the 13th, a scary day for people who are superstitious or just have an irrational fear of the number 13 (Triskaidekaphobia). Of course, it's been a rough year for a lot of people and the general consensus is that Friday the 13th (which eerily falls on a Friday this year) is just another scary day in a whole year full of them. But it can't hurt to be extra careful today anyway: don't walk under ladders, avoid walking beneath any crane lifting a piano or a safe, and definitely don't have sex—Jason Voorhees hates sex.
