Most people don?t enjoy using portable toilets, but the experience turned especially harrowing for two women at a Newark ball field.

Porta-Potty tipping has become a popular pastime for vandals with video cameras. While it may be hilarious to pranksters to post the videos on the Web, it wasn?t funny for the two women targeted in the Newark incident.

According to the Newark Fire Department, two women were inside the portable toilets Thursday when pranksters tipped the units over. The women became stuck inside until firefighters came to free them.

Fire officials say the women were covered with waste and lye and had to be hosed off. Both women refused to give their full names and declined medical treatment.
