I'm busy pondering life's little mysteries:

How come no matter how much I clean, my room is never actually clean?
How come they always advertise loo roll with kittens and puppies? I don't want to rube either on my bum.
How come the more of a man's penis you can see on the street, the more likely it is that he's gay?
Why do bottles of pop have that flower shape at the bottom?
And so on.
