Here's an anecdote that validates the possibility. But it doesn't say anything about how often the phenomenon occurs. My only argument is with the use of the word "often."

This story was just reported this morning.
Man Has Nail in Brain for 36 HoursI witnessed the interview of the guy with the nail in the brain. He knew the nail gun went off, but didn't know the nail went in his brain. Only after a day when experiencing nausea did he think to get medical attention. When they came back and told him there was a nail in his brain, he didn't believe it.
For the record... the interview was AFTER the nail had been surgically removed. The guy seemed perfectly fine, and joked about how he wanted the nail as a souvenir.

Edeilson Manoel do Nascimento holds an X-ray showing a knife that was inside his skull, at the Hospital das Clinicas in Recife, Brazil, Sept. 23. Nascimento is recovering nicely after a team of surgeons removed the 4-inch knife that had remained lodged in his head for three years after a bar fight. Severe headaches led him to have the knife removed, according to press reports.
