In the past seven seasons of Supernatural, Sam Winchester has had to face some freaky creatures, including all manner of demons, spirits and the undead.

Now add to that list his ultimate nightmare: clowns.

On the Friday, Feb. 10 episode, the Winchester brothers investigate the Plucky Pennywhistle's Magical Menagerie pizza chain in Kansas. Turns out some local children visited the eatery, drew a picture of their worst fear, and some embodiment of that fear killed their parents. As any Supernatural fan knows, clowns are Sam's No. 1 phobia, and he's left to face a couple of irate clowns while Dean (Jensen Ackles) hunts down the source of magic.

Who are TV's hottest men?

"The guys playing the clowns were both extremely nice," Jared Padalecki, who plays Sam, tells TVGuide.com. "One of them I'd already met before. A big, burly, powerful, awesome, nice fellow. The other one was an actual guy who had worked with the circus before. But once you deck them up and doll them up in costumes, they look pretty scary. There's a big twist to their costume, which you'll see. They're certainly not just big, happy clowns."

Check out these exclusive first-look photos of Padalecki taking on two bozos and be sure to read what he says about his personal relationship with clowns:

Yikes! We wouldn't want to meet up with those two anywhere, much less a dark ...warehouse? garage?

In real life, Padalecki loves clowns. "I think there's real fear in my eyes in the fight scenes, but it's the real fear of getting hurt or beat up," he says. "But I've never been scared of clowns. I used to love clowns. I think I spent a few Halloweens as a clown. One of my favorite clowns is from IT, the movie."

Supernatural airs on Fridays at 9/8c on The CW.
