The only reason establishments are able to properly function. The only reason the Breakfast Club is what it is. The only reason our world is a some-what sanitary place. My strange affection for custodians cannot be placed into words, as they are too SKILLED for human comprehension.
It was no coincidence that my best friend's and my lockers were smack dab between the custodians' lair...
