Before I found any lyrics site giving the lyrics for Lady Gaga's song "So Happy I Could Die", I thought she was singing "So happy I could die. I'm A Samurai." On finding the real lyrics from a site, I found she is only saying "So happy I could die and it's alright." That is way "lame" compared to what I first thought I heard. Possibly I've never visualized anything else so wildly ludicrous as Lady Gaga posing as a Samurai!
