While some students fill their hours studying for finals or writing papers in solitude, others have found a higher calling: the prank. It's an art form extending back centuries, or at least to the 1980s.
With the aid of some fun-loving (or helpless) professors, pranksters have invaded the halls of higher learning in the guise of ninjas, superheroes or six-foot bunnies. Those with foresight made sure everything was recorded and put on YouTube.
Before you discount these jokes as artless and silly, check out the videos below. Yes, they're silly, but the craftsmanship that went into some of these elaborate performances may surprise you.
Have you ever captured a prank on video? Tell us about in the comments. And please, don't try these pranks at home.*
*Try them in a lecture hall, obviously.
