The song is called "Prisencolinensinainciusol," written by Italian artist Adriano Celentano in 1972. Recorded by Celentano and Claudia Mori in an American accent, it sounds like it should be English, but the lyrics are pure gibberish. I posted this about four years ago, and it was probably the most popular post I ever had, but then it was lost when I moved back to Blogger. Now YouTube member emeryemery has added subtitles, as best as he can figure them out. Hilarious! Hope you enjoy it!
