It was my girlfriend at the time that mis-sang the lyrics. I laughed and pointed out her mistake. She argued with me for a week about it and I finally was able to show her. Then she HATED me after that and said that it made her think of all of the times that she sang that really loud at parties and knew now that people were laughing AT her instead of with her. She said that I never should have corrected her and caused her embarrassment.
