"Dozens of students at Ravena-Coeymans-Selkirk High School have been suspended for sticking Post-It notes throughout the hallways of the school overnight.

The students took about 5,000 packs of the notes into the building and posted them throughout the hallways Thursday night. They wrote messages like "Seniors" and "poop." They used Post-It notes because they didn't want to damage the school, said Karin Beswick, an 18-year-old senior who planned the prank."
