You are Useless.

What's the most useless thing in my flat, eh?

My instinctive answer to this question would be Pook. However, Pook is only useless because she's never in the flat.

Conversely, I know Pook's answer would be me, as would Ben's. (He told me this, the traitor. He'll be getting no more of my magic pesto chicken.)

My next choice might be the vacuum cleaner. It has no effect on my bedroom carpet. But on second thought, it's not bad on the hardwood floors.

Then I wondered about Marv. He makes a mess, leaves my computer on, and can never remember our security code to let himself in. But he keeps Ben quiet when they play Pro Evo, so he's not all bad.

So I guess my final answer would be our grill. It's been broken for months, and not even Dad can fix it. I'm sure that having to fry everything has contributed to my shocking Wii Fit age. I hate you, Broken Grill. You made me fat.
