My ex had one and if you didn't secure smaller items that it could run away with, you were screwed. Keys, chap stick, socks, etc. Luckily she had the same hiding spot (underneath a living room end table) so once a week my ex would move it aside to collect items she didn't even know she was missing.
Sneaky little bastards, but highly entertaining.
