From the Daily News:
Word went out on the Internet the night before that this year's annual prank day at Richmond Hill High School would be one to remember.
Bedlam erupted just before 10 a.m. when eggs and anything else students thought to bring to school started flying, witnesses said.
"They threw rice, barbecue [sauce], flour, baby powder, Silly String, shaving cream - everything you could imagine," said sophomore Jose Dominguez, 16.
Stephen Gonsalves, 18, was arrested for possession of a knife. Nine other students, ages 16 to 19, were arrested for criminal mischief, trespassing and disorderly conduct.
