The Navy Times has a tale of serious toilet woe aboard the USS George HW Bush aircraft carrier, which is currently deployed to the Persian Gulf. The $6.2 billion carrier has 130 bathrooms with 423 commodes, but many of those commodes are frequently on the fritz at any one time. Some choice details: 
 -  At least twice since the ship deployed in May, all 423 commodes were out of service simultaneously. Most times, it's just sections that go down.
-  Sailors blame the ship's vacuum system; the Navy blames sailors flushing everything from clothes to hygiene products.
