Cheerleader camp turns ugly after one high school squad decides to play a prank on a rival squad - delivering a pizza with one topping, human feces.

According to reports, a group of cheerleaders from Fossil Ridge High School in Texas sent a pizza to a rival group from Keller High School on the last day of camp at the University of Texas at Arlington.

It didn't take long for the girls to notice that the delivery was anything but a friendly gesture. After an hour of inspection, the Keller squad reported the pizza to the Fossil Ridge sponsor claiming that the Fossil Ridge squad put human feces on the pie.

After investigating, four cheerleaders were sent home - their pending punishment is unknown.
