At the beginning of the song, a bag of balloons is bought. Most normal balloons are packaged in multiples of 5 or in fractions of a gross. 99 is neither a multiple of 5 nor a fraction of a gross, so why are there only 99 red balloons? Shouldn't there be 100? Did they buy a 100 count bag and get shortchanged by 1 balloon? Did 1 balloon have a leak in it? Did one balloon pop during inflation? Hell, did they buy a gross bag of shitty balloons and wind up with 45 defective ones? What the hell happened to the extra balloon(s)? I need to know.
