There’s a girl named Jacinda Cambray in Levittown, Pennsylvania, and she had her sweet 16 birthday party on Sunday night. Everything was going great — until it started raining.

Not water, though. It started raining poop.

Apparently a plane was flying overhead and emptied out its waste, which showered down on the 40 people at the party.

There were about five planes flying in the area at the time, and the FAA is still trying to figure out which one dropped its feces over Jacinda’s party.

They aren’t allowed to do that, by the way. Airplanes have to get rid of their waste at airports.
