LeBron James and Ricky Gervais are among the celebrities who took to twitter to either celebrate or joke about Friday the 13th.

FRIDAY THE 13TH TWEETS

For the first time in 11 years, the 13th of October has fallen on a Friday, and Twitter is here for it. “Love #FridayThe13th!! Halloween is coming and I can’t wait! 👻🎃🙀,” the star basketball player wrote. “Nothing bad will happen just because it’s Friday the 13th. That’s primitive, superstitious nonsense. And anyway, God will protect you,” quipped Gervais.

Millie Bobbie Brown tweeted in anticipation of Stranger Things season 2, which released a full length trailer today. The show returns Oct. 27.

A lot of companies and shows got on board with the typically unlucky day to promote special deals, or just used it as a way to interact with customers. Hulu and American Idol posted fan polls about superstition, while Sony asked fans to name some of their favorite scary PlayStation games. Paramount Movies let fans know that its Friday the 13th 8-movie bundle is for sale.

Ryan Seacrest added, “I know today can be unfortunate for some but I will take #FridayThe13th over Monday any day.” The U.S. Olympic team wished luck to it’s athletes who may be competing today.

And PETA used the day to remind folks that black cats are less likely to be adopted because of the superstition that they are unlucky, and encouraged cat-lovers to adopt black cats.
