Best prank ever

BLACK RIVER FALLS, Wis. - Students may be struggling this time of year to get back into the groove of school, but in the Black River Falls School District they're up-to-speed with pranks.

The district in western Wisconsin canceled classes Monday after someone deflated the tires on all 18 of its school buses.
The vandalism happened between 7 p.m. Sunday and 5:45 a.m. Monday, district transportation director Jeff Walker said.
He said they tried to fix enough buses to just delay the start of school by two hours, but they couldn't so classes were canceled.
