ARGH...these so-called lyric writers really just made too much work for everybody who might want to sing along.

The REAL lyrics to the song are:

POPCORN POPCORN POPCORN POP
CORN POPCORN POPCORN POPCORN
POPCORN POPCORN POPCORN
POPCORN POPCORN POPCORN
POPCORN POP
CORN POPCORN POPCORN POPCORN
POPCORN POPCORN POPCORN POP
CORN POPCORN POPCORN
POPCORN POPCORN
POPCORN POPCORN POPCORN

(repeat in like style, matching syllables with notes until the song runs out or until you realize you have better things to do, whichever comes first)

what?
