I love senior pranks, most usually end up with the students getting in trouble. This one seems relatively innocent.

Seniors at Ann Arbor's Skyline High School put it up for sale last night on Craigslist.

The asking price? $7,540,765!

That's actually a pretty good deal, as stated in the ad.

Ever want to buy a high school? Now is your chance! You get the mental hospital design, mixed with the long white hallways and 2,500 staff and students. What a bargain!

To follow it up, seniors also posted 'for sale' signs outside the school.

Thankfully, the school officials have a sense of humor and are laughing along with the students on this one.
