Speaking of stupid head tricks:

A California public school barred an 11-year-old boy from class for 2 1/2 days after his mother colored his hair green to reward him for good grades.

“He had asked for it and I told him that if he got nothing less than a ‘B’ on his state report, I would do it,” parent Cathy Small, who has brown hair, said on Tuesday. “I don’t see anything wrong with it. It’s not a permanent thing.”

Officials at the Natoma Station school in Folsom said the grape-green coloring on 11-year-old Alex was distracting other students, but finally relented and let him back — with green hair — on Monday.

Stupid educators.

Off with their heads!
