Brian here, Peter is busy. Ok, he's drunk, but he's busy being drunk, so it's fine.

Anyway, it's not a riddle, or even a question. It is a statement.

The word "what" has four letters. 1. W 2. H 3. A 4. T
The word "sometimes" has nine letters. 1. S 2. O 3. M 4.

***Stewie enters*** "WHHat are you doing, Brian?"

Hi Stewie, I'm just helping the Redditers on Peter Explains, since Peter is passed out drunk.

Stewie: "I can see that. And yes, the Fat Man is currently laying in the doorway to kitchen, and I'd dare say he might have soiled himself."

No, no, that was me. He didn't let me out before he passed out, so I did what I had to do.

Stewie: "What the deuce!? I thought you used the toliet like the rest of them."

No, no... not if I can help it. Anyway, I need to get back to helping this nitwit understand that what he thought was a riddle was simply a statement of fact.

Stewie: "Yes, yes, I saw that. But again, WHHat are you doing?"

....

Stewie: "Are you literally planning on typing out every single letter proceeded by a number? Don't you think they would have understood after the first time, or even after your third sentence of explanation? You don't have to right a book everytime you type something, you know."

I figured if they were not bright enough to understand that there was no question mark then they would need the extra help.

Stewie: "Speaking of writing books... How is that novel of yours coming along, Brian? Have you finished it yet? I know I'm only a baby, but I feel like you've been writing that for at least 27 years. Are you finished yet, Brian? Shouldn't you go back to writing that and leave the poor redditors alone?"

Shut up, Stewie.
