Switzerland Accidentally Invades Liechtenstein

This story in the New York Times actually made me cackle with glee:

What began as a routine training exercise almost ended in an embarrassing diplomatic incident after a company of Swiss soldiers got lost at night and marched into neighboring Liechtenstein. ...

Interior ministry spokesman Markus Amman said nobody in Liechtenstein had even noticed the soldiers, who were carrying assault rifles but no ammunition. ''It's not like they stormed over here with attack helicopters or something,'' he said.
