What better way to mark Friday the 13th than with free food?!
Firehouse Subs said on Facebook that if your name is Jason, Crystal, or Richard, you can get a free medium sub on Friday with any purchase.
Why those three names in particular?
The restaurant chain is paying homage to the 'Friday the 13th' horror movies.
Jason, of course, is the iconic hockey mask wearing killer, while Crystal Lake is the setting for several of the films in the franchise.
Richard is for Richard Brooker, an actor and stuntman who played Jason Voorhees in 'Friday the 13th Part III.'
To get your free sub, visit any Firehouse Subs and provide your photo ID that shows your name is Jason, Crystal, or Richard.
