20. Belgium
Belgium is a small country yet, it is packed with an army of humorous citizens. Belgians love telling jokes in most of the gatherings to add color to what’s being discussed. Belgium is one of the friendliest countries to Americans. Not only because Belgians and Americans get along too well when it comes to puns and hardcore jokes. It’s because both of these nations share a common mindset. Back in the age of World War II, they exchanged influential tactics to surpass the Nazis.
