Paddy is walking along the street leading his donkey when the donkey has a massive coronary and dies, keeled over in the middle of a busy street.
To Paddy's horror he nothices that the dead donkey is sporting a huge (even for a donkey) erection. Paddy quickly whips out his pocket knife and cuts off the offending organ, rolls it up and stuffs it in his pocket and wanders off trying very hard to look nonchalant.
Walking past a high brick wall, Paddy pulls the donkey's cock from his pocket, lobs it over the wall, and heads for the pub and a well deserved Guinness or four.
Unfortunately, unknown to Paddy, the wall over which the erection had flown belonged to the local convent and the flung penis has landed upon the path around which the nuns took their exercise, and it is not long before one of the sisters spots said object. Hitching up her robes she runs (in a most unseemly fashion for a nun) back into the convent and straight to the Mother Superiors office.
After banging on the door and receiving permission to enter she takes a deep breath and says "Mother Superior, come out into the garden quickly, come and see what the murderin' Protestant bastards have done to Father O'Connor!"
