NBC Philadelphia reports:
A group of Wisconsin students was all ready for their prom, the girls in their elegant gowns and the guys decked out in stylish tuxedos. They decided to pose for group photographs while lined up on a pier that extends over a lake in Oconomowoc, about 30 miles west of Milwaukee.
As the group crowded onto the pier Saturday, one person called out that he just heard two cracking sounds, and everyone else stopped, said Josh Orne, 17, one of the students. Without warning, part of the pier gave way, and about half the students dropped feet-first into the water.
"The girls starting screaming and basically the guys started laughing. Because it took us no time to get ready, and it took them all week to do it," Orne said.
And a few more shots:
But don't worry, you guys: the kids dried themselves off and had a good time anyway.
