When dealing with kids, it pays to be specific.

Talk about your servant leadership! Principal Scott Davies really went out on a limb to encourage his students to read (Well, maybe not a limb, but at least it was a roof in December.)

The principal spent a frigid night on the roof of Harrington Park School in Harrington Park, N.J., after students met his challenge to read 10,000 books months before he expected them to. The school has about 700 pupils in kindergarten through eighth grade.

Davies had agreed to let them choose their reward, and they decided to shave the school's "HP" logo in his hair and send him on a rooftop camping excursion.

Davies, 40, headed up after school ended Thursday with a tent and a sleeping bag.

"I knew it would be cold. But I didn't know it would be that cold," he said.

Temperatures plunged into the 20s Thursday night and Friday morning, but Davies -- somewhat steeled by several years of living in Montana -- said he managed to get a few hours of sleep.

I'm not too sure he would have survived in Montana, but at least the students brought him hot chocolate.

This is one brave soul. I'm not sure our roof would hold up under the strain if anyone actually camped out on it, since I'm pretty sure it has the structural integrity of swiss cheese.

Saaaaaa-LUTE!
