Since launching in 2010, Snickers' "You're Not You When You're Hungry" television ads have been virtually inescapable, with everyone from Betty White to Rowan Atkinson to Danny Trejo encouraging us to chow down on the popular chocolate bar. Yet somehow U.S. audiences have largely been spared the terrifying version featuring the Joker -- that is, until now.

Warning: Be prepared to drop that delicious blend of roasted peanuts, nougat, caramel and milk chocolate, and flee to a space place. Preferably, somewhere with a door that locks.

Debuting in 2013 in the Middle East, the spot features four friends playing cards, unfortunately one of them "gets a little bit crazy" when he's hungry, transforming into the Joker. But not just any Joker: It's a blend of Cesar Romero's Clown Prince of Crime and the long-faced supervillain drawn by the likes of Marshall Rogers and Jim Aparo.

And that laugh. It's chilling and seemingly endless, making the spot feel as if it stretches well beyond its 55 seconds.

We may never know why the commercial resurfaced after nearly three years, but one thing is almost certain: We'll never sleep well again.
