Sticky note prank!

Five students from a high school near Indianapolis are in hot water over their senior prank. Check out the colorful display they left behind at Cascade High School--all done with post-its.

Ten-thousand sticky-notes covered doors, trophy cases and even spelled out 20-12 on the gym floor.   The students say a board member gave them a key to get in.  And the head custodian helped coordinate timing.

But the superintendent handed down the punishment because they shouldn't have been in the school.  The custodian lost her job.

Traffic jam prank!

A senior prank near Saint Louis infuriated drivers during the morning commute. At least 50 seniors from Francis Howell High School road bikes, skateboards and scooters to school on the highway.

Traffic was backed up for miles.  Technically, they didn't do anything illegal, but plenty of people were angry about the traffic jam.

Senior Cooper Cathcart says they thought it would be funny to make students and teachers late for school.  But Missouri Highway Patrol Sergeant Al Nothum says it was dangerous, and they could have caused accidents.

The principal issued a warning to students threatening to ban them from graduation, if they tried any more senior pranks before the end of the school year.
