Understanding how American Culture Looks to Outsiders

Hugh Laurie's song for America - A bit of Fry and Laurie - BBC sketch comedy

I didn’t find this clip funny especially the ending part. I think even though Americans are very patriotic and very proud of their country but still there is much less racism in America than Europe.
Some other cultures and countries might have a not very positive look at American politics, but America’s music, literature, style of life, Movies, and technology has had very positive influence in other cultures over the years. American music especially has been very popular across the world. “American contemporary music can be heard all over the world, such as through Channel V, VH1 and by artists such as Jimi Hendrix, Chuck Berry, Elvis Presley” [1] America in its literary history has had “eleven U.S. citizens that have won the Nobel Prize in Literature, most recently Toni Morrison in 1993. Ernest Hemingway, the 1954 Nobel laureate, is often named as one of the most influential writers of the twentieth century.”[2]
I believe all cultures make fun of each other because of misunderstanding and prejudice. I think that is the human subconscious that everybody wants to be the best but unfortunately a lot of time to achieve that wrong concept, the shallowest and easiest way is making a bad view of others by humiliating them through jokes.
