|Bronwyn Bishop (is not amused)|
They were ejected from Parliament for laughing by the frowningly stern speaker Bronwyn Bishop (who is a member of the ruling Liberal party).
Not everywhere do politicians find laughter so objectionable. This video from the Swiss Parliament is delightful, even if you don't understand German.
In fact the politician in the pinstriped suit, Hans-Rudolf Merz, is talking about meat products. He found some of the bureaucratic language amusing and obviously his Parliamentary colleagues did too!
