When I was about 3 or 4, my older sister (about 20 at the time) thought it would be funny to have me watch JAWS. Because of this, I thought the sound sharks made was the JAWS theme. Doggies go "bark," sharks go "dun dun...dun dun..."
My sister's boyfriend was quite bemused when I announced my frustration that the sharks weren't "singing" at the aquarium the next week.
