The USS George H. W. Bush is under maintenance in Portsmouth, Va,. to prevent clogging in the ship’s 493 toilets by putting in “anti-snag” devices, the Newport News Daily Press reported over the weekend.

The stopped-up toilets have been causing frustration since the ship first deployed in May 2011, the newspaper reported, with workers finding things like shirts, underwear, socks, hard-boiled eggs, bolts and mop heads jamming the pipes.

“You’d be amazed what gets flushed down the toilet of a ship,” an engineer said. “Anything that can fall out of a pocket or off a person, like sunglasses.”

So, remember: Always pull up your socks.
