I read diary of a wimpy kid #6. Greg put signs up with permnant green ink, then when it rained the signs got wet so the green ink showed on the school wall, then the intercom called every student for the investigation with a lie detector, and last Greg had to clean the green ink off and after that the police came to Greg's house and left a note since he and his family wasn't there.
