The story:

My family and I were on a long road trip and my dad put this tape in the radio. My sister and I, thinking we were cool, started singing the chorus. Those were the three versions in one sitting we heard. Every time that line came around, my parents would shout over both the radio and my sister and I the real lyrics. To this day we still laugh about it. duh-duh-duh!
