Sittin' on Taco Bell

The story:

My younger sister & I were both small children sleeping in the back of my mother's car, & this song came on the radio & we, so far away from the speakers & half asleep, heard it say "Sittin' on Taco Bell" The next time that line came up we both said it & mother said "No, no, no" laughing, "It is 'Sittin' on the dock of the bay'" I laughed & said "O I imagined sitting on Taco Bell, you know, one of the ones with the pointy roofs, & scratching my butt" I will never forget the "Eeeewww!!!" which sprung forth :p .
