I used to think (I was about 7) that the Spice Girl's song "Tell Me What You Want" was "Minni Miini Maa" or some other dememted thing. I went around singing nonsense lyrics thinking I was "oh so cool". "Minni minni maa maa oh ma, yo minni maa.." SO stupid..and I never even understood the weird glances I was recieving until about 5 years later!
