I am the reason your hair is standing on end. I am the bad smell in the cupboard. I am the wad of gum that sticks in your hair. I am the furry food in the fridge; I am the very fur that inhabits your tormented food. I am the cat hair in your coffee. I am the blue mushroom in the rear view mirror. I am the reason you can never find your car keys. I am the cellphone that turns on and off at the drop of a hat... your hat.
I am Llwy-ar-lawr. You will learn to fear my wrath... er, my breath, for it smells like old socks. Really, really old socks. However, if you don't, nobody will care.
My accomplishments, or lack thereof, may be viewed below. My lack of existence may cause lots of stuff to explode, which may pose a danger to your lack of failure to lack nonexistence. You have been warned.
