Why does switching the batteries around in a remote make it work for a little bit?

This always seems to work with most electronic, battery-powered devices.  The most obvious reference being a remote control.

The electrical contacts on the battery and/or battery holder build up a thin layer of corrosion that resists current flow. Moving the batteries around scratches the contacts and exposes fresh metal, improving conductivity.
