This is one way to end your time in high school with a bang.  A foul, nasty bang.

An 18-year-old senior at Stephen Decatur High School in Worcester County, Maryland was arrested on Monday . . . for repeatedly MAILING POOP to his vice principal.

The vice principal got a package with cow and dog poop inside on April 30th, and called the cops.  They told the local post office to be on the lookout for suspicious packages addressed to him.

Two days later, the kid tried to mail two MORE packages of poop . . . but the postal inspector was paying surprisingly close attention and wrote down the kid's license plate.

The cops tracked him down on Monday.  He was arrested and charged with three counts of disturbing activities at school and three counts of molesting a school administrator.  Yes, you heard that right . . . that's what they call it.

The school also suspended him for 10 days.  He didn't give a reason WHY he was sending cow and dog poop to the vice principal.
