I'm an indian outlaw, wee-chee wee-chee wah-wah!

The story:

Actually, the offender was my younger sister, Anetia. I can't remember exactly where we were. I think we were in my room and I had the CD on. She was about 9 at the time and when it came to the verse, that's what she sang! I was LAUGHING! I asked her what she was singing and she said it again. She said, "Aren't those the words?" I told her what the words were and she started laughing. She said she didn't know what "Wee-chee wee-chee wah-wah" meant, but she just figured that if he was an indian outlaw, he probably just said something in Indian all of a sudden!
