An excellent post on the Smoking Gun:
In a bold and bizarre attempt to destroy evidence seized during a federal raid, a New York City man grabbed a flash drive and swallowed the data storage device while in the custody of Secret Service agents, records show.
That’s going to hurt. Soon.

Yeah, the biggest problem is he’s a mac user, so after he finally shits the thing out his colon will complain that he didn’t properly eject the drive first.
Good one, Brian. But my Windows box always does the same thing.
I’ve seen some flash drives- PNY makes one that’s impossibly tiny. I could see swallowing it. But my cheapo- Staples(tm) brand one with the chrome ring is definitely not suited for spur-of-the-moment concealment in the digestive tract.
