(a typical day in the Comments box)

Who: first!

What: whoopee, first!

I don't know: first for the first time! Yay!

Abbott: wait a minute, Who's on first!

I don't know: What? I thought I was first.

Abbott: No, Who is first. What is second.

What: OK, got it. I'm second. Who's first.

Costello: @ What, I don't know.

Abbott: @Costello, you're mixing up the first with the third. Who's first. Third: I don't know.

Costello: @Abbott, if you don't know, just let it drop. What's the point, anyway?

Abbott: @Costello, I know the order, but I didn't know What's the point. What was second.

Costello: @ Abbott, that's exactly what I've been asking you! Who was first? Who was second? Who was third?

Who: no, I was just first. What was second.

Costello: I DON'T KNOW! YOU TELL ME!

I don't know: tell u what, Costello? What's the question?

Abbott: no What's second.

Costello: I don't know.

I give up: What? I'm still here!

What: OK, I give up.

I don't know: What, are you giving up?

What: I'm not giving up, Costello is.

I give up: no, that's me. Costello quit, I think. I don't know why.

Why: I'm here! Who was first?

I give up: How did you know that?

Why: What?

What: Yes?

Sadly, this went on for more than 1600 comments. Some say the posts continue even today. At least we know Who escaped the room.
