Students at the University of Alaska have taken to a weird -- and costly -- ritual: flushing socks down the toilet.

Campus officials are perplexed by the hundreds of socks that have made their way into the UAF Fine Arts Complex sewer system - not to mention annoyed at the $15,000 worth of damage they've caused.

According to the University's maintenance superintendent, the socks are children's sizes and continue to be flushed, despite signs placed in the bathrooms asking culprits to put an end to their shenanigans. In fact, the "please stop" signs prompted an additional 40 flushed socks.

Catching the sock flushers is difficult because cameras in a bathroom are illegal and nobody can see what's happening behind closed doors. Officials say they'll continue dealing with the problem, but are unsure about how to make it stop.
