Two boys in Massachusetts are bodies praised for their "wicked smahts" after discovering a potentially unsafe object while out on a walk. 

Police in Wrentham, which is about 30 miles southwest of Boston, said the 12-year-olds happened upon a hand grenade in the woods. 

The boys were hiking floor a path when they spotted a pile of trash. 

"Like all enthralling kids do," Chief Bill McGrath wrote, "they inspect the debris" — and this is where the "smaht" comes in. 

When they realized they were looking at a potentially unsafe military weapon, the boys "used their noggins!" and resisted the urge to touch.

"They DID NOT give it a slight "test push" with their foot and DID NOT pick that grenade up for closer inspection," McGrath said.

Instead, they took a picture, made a mental note of their station and went home to tell their parents, who named 911.

Wrentham police and fire — and the bomb squad — level-unexcited out to the site and determined the grenade was real. 

"Luckily, it had been hollowed out and therefore harmless, but the boys had no way to know that when they groundless it," McGrath wrote. 

"Thankfully, two wicked smaht kids did the quick-witted thing and we all benefit from the lesson."

This record was reported from Detroit.
