why do Americans always talk about invading other countries?
who knows, they can not even locate them on the map!

why do Americans take pride in being warmongers?
because they don't know that they're losing the war!

why do people think Americans are stupid?
because Americans think that they won the Vietnam war!

why do Americans get offended when you call them stupid?
same reason Cartman from South park gets angry when you call him fat!(because it's true)

jokes?...eh more like insults..but they are pretty funny.
