Dirty Deeds and the Thunder Chief

The story:

I was with my friend Kelly, and she was singing the song. I was also, and when it came to those words, I was barralling them out and she became silent. I kept on singing and all she could do was look at me. Then she said,"What did you say?" I repeated the words "Dirty Deeds and the Thunder Chief." She busted out laughing and then asked me if I had ever looked at the name of the song. Needless to say I was told, but not after extreme embarrassment and years of singing the song that way and I mean years.
