Unless you're a mattress tester, you should never fall asleep on the job. That's particularly true if the job in question involves breaking the law.

There are a surprisingly high number of criminals are found sleeping in houses they broke into. Actor Robert Downey Jr. made his longtime drug addiction even more embarrassingly public on July 16, 1996, by accidentally falling asleep in his Malibu neighbor's house — in a child's bed, no less, and there are a few lesser known examples:

• Mark Smith snuck past a homeowner while she was ironing, and was discovered hours later when she saw his legs sticking out from under her bed. When the cops arrived, they found the criminal passed out and were unable rouse him from his drug-induced slumber.

• Dion Davis grabbed a bag of jewelry from his victim's house before passing out right on the bed with his stolen goodies beside him. He didn't even wake up even when the maid discovered him or when the police arrived and started taking pictures.
