Billy Ocean's song "Caribbean Queen" was on the radio almost every morning before I went to school one year. I heard it often, so you'd think I'd know the lyrics...
The first line, in my head, was "She dutched by me and fainted on Gene". I'm not sure what I thought "dutched" meant; the mental image was that she slipped past the first guy and collapsed in the arms of his buddy.
The chorus was "Caribou queen / Now we're sharing the same tree". No, I didn't think she looked like a caribou, although I did imagine them sitting in a tree together. She might have been wearing caribou hide and fur, Inuit-style.
For the record, the correct versions are "She dashed by me in painted-on jeans" and "Caribbean queen / Now we're sharing the same dream". (Even the lyrics websites disagree on that first one-- depending on who you talk to, you'll be told it's "dashed", "danced", or "brushed".)
