No dogs, wombats OK

I just love Rule 51 of the Oxford Union Society Rules:

Rule 51: Dogs

Any Member introducing or causing to be introduced a dog into the Society’s premises shall be liable to a fine of £5 inflicted by the Treasurer. Any animal leading a blind person shall be deemed to be a cat. Any animal entering on Police business shall be deemed to be a wombat.

Why a wombat I do not know, but one of my ambitions in life has just become to take a wombat into the Oxford Union Society…
