Interesting fact:

One of the smallest countries in the world is Liechtenstein – only 37,000 people live there. That’s roughly the same size as Atlantic City in New Jersey! In fact, it’s so small that the Prince of Liechtenstein invites the WHOLE COUNTRY to come and drink a beer at his castle every year. And in 2007 Switzerland accidentally invaded Lichtenstein when one of their battalions got lost during a training exercise!
