One more question, Bob. Would you explain why the MPs pop up like jacks-in-boxes? Is this how they are recognized by the presiding officer? Oops, I guess that was 2 questions.

Not sure, though one of my theories is so that the Pm or the minister responsilble is not standing up on their own, possibly due to the threat of Assassination, which go right back to the Gunpowder Plot, or it could be out of sheer courtesy.
