If you're easily spooked by the sight of creepy clowns, you might want to avoid a select few Burger King locations during the evening of Halloween. Conversely, if you don't mind dressing up as a creepy clown, you could earn a free Whopper sandwich. 

Through its You Tube page, Burger King announced a promotion to give away hundreds of Whoppers to those dressed as creepy clowns. Unfortunately (or fortunately depending on how you look at it), the promotion is limited to the first 500 customers after 7 p.m. Tuesday at selection locations near Miami, Austin (Texas), Boston, Los Angeles and Salt Lake City. 

Burger King is also encouraging those participating in Tuesday's promotion to send pictures using hashtag #ScaryClownNight.
