You've heard of Elf on a Shelf? How about Sheriff on a Shelf?

The Polk County Sheriff's Office posted on social media Tuesday that it's selling, for charity, figures of Sheriff Grady Judd similar to the Elf on a Shelf craze from recent years.

"You know you want one - your kids are guaranteed to behave with this guy watching over them," the Sheriff's Office said.

The figures have to be bought in person, cash only, at these Sheriff's Office locations. They are $15.
