NORMAL - Police are looking for two teenage boys who hit an unsuspecting woman in the face with a pie when she opened her front door.

The woman told police she answered her door about 4:45 p.m. Monday in the 2800 block of Greyhawk Drive, a Normal police report said.

A boy asked her if she was familiar with the mathematical term "pi," and then hit her in the face with a pie, police said. The other boy used a video camera to record the assault, police said.

Police believe the victim, who did not know the pair, was selected at random.

There were no arrests by early Wednesday morning, police said.

Greyhawk Drive is in Eagles Landing subdivision in northeast Normal.
