Back in the olden days when you had to type a series of letters and numbers into your Nokia phone to get a custom ringtone, mine was Popcorn. It was great for a few years, and then the Crazy Frog ringtone fad hit Europe and the second single released under that brand was, you've guessed it, Popcorn. I had to change it after that, although I still like some of the original versions.
