i think pi is pretty cool

I didn't know this before you brought it up, but looking around online, I see that the song was originally called "987", and plays in one bar of nine, one bar of eight, then one bar of seven...and 987 is a Fibonacci number?
 
i don't know dude...I'm like...a journalist.

but the syllable pattern in the verses is a fibonacci pattern

1, 1, 2, 3, 5, 8,..then it descending 5, 3, 2, 1, 1, then up again...2, 3, 5, 8, 13, then down 8, 5, 3
 
I did my senior project in high school on the classical use of the golden mean and fibonacci numbers in the proportions of architecture in both the ancient world and during the renaissance.
