"My milkshake brings all the boys to the yard, and their life, is better than yours"

The story:

I had the lyrics right at first, until my best friend absolutely convinced me that I had it all wrong. She said that my version made no sense!! (ha!)She was so sure of herself, whenever I sang along, I sang it that way. One day I was at party with a bunch of other friends just belting it out when they all corrected me and cracked up. God I felt gullible.
