LONDON, Ont. -- A former London Catholic high school student's flash photo shocked students and staff when they cracked open their shiny new yearbooks.

In a photo of the news team at Mother Teresa secondary school, the group that produces the morning announcements, one student decided to flash more than his pearly whites for the camera -- choosing, instead, to unzip his pants and show off his genitals.

Not aware the yearbook contained any nudity, staff handed out copies at the school of about 1,300 students last Friday.
