Seņorita mosquito, who's that girl

The story:

My sister and I would sing this song over and over again because we were fascinated by this song and thought we were very interesting because we thought our Englisch was so very good.. (we are Dutch and were about 8 and 9 years old) We later discovered it was the wrong tekst when we heard it on MTV. We always thought people were laughing at us because our englisch was so good...now we know better and are ashamed...I think we sang it a thousand times, while going to school and at the schools playground during lunchbreak...
