Usually a school prank is a harmless trick or a clever gag designed to get attention and hopefully some laughs. But some pranks go way beyond what is considered amusing and venture into the sick and twisted territory. That would be the case with the prank 19-year-old Myles Frost pulled at Glenbard East High School near Chicago last year.

Frost has just been convicted of misdemeanor charges of animal cruelty and criminal defacement after scattering mutilated mice and a decapitated rat around his school campus in 2007. He left the rodent corpses in the stairwell, the bathroom, the drinking fountain and in the slot of a vending machine.

"Even if it's a prank, to say it's in bad taste would be an extraordinary understatement,'' said Judge Robert G. Kleeman. Judge Kleeman ordered Frost to undergo a psychological evaluation and serve two years probation. During the trial, Frost's attorney denied that his client was responsible for the disgusting prank, but a school official and the police say that Frost confessed to them.

According to his lawyer, Frost is continuing his education and has high hopes for his future. "He has dreams of working with animals -- that's really what his dream is," said Frank Fanella. I am sure his court-appointed psychologist will be very interested in hearing about those dreams.
