The Pittsburgh Penguins were looking for 250 students to help with an important task and there was only one major requirement: you must know how to flush a toilet.

Construction neared completion on the NHL team's new arena, the Consol Energy Center. But like with any new arena or stadium, officials needed to simultaneously flush all the toilets and urinals to make sure everything is working. The Penguins called the June 10 event the "Student Flush," a spinoff of their popular ticketing program known as "Student Rush."

Students already involved in the ticketing program could enter for a chance to win. Students had to be 18 or older to participate in the "flush-apalooza."

In all, there were 400 flushers, including some construction officials, on hand that day.
