There was a Nun who kept saying BLOODY. Every second word she said was bloody. The other Nuns weren't too happy about this so they decided that next time Sister says bloody all the Nuns would get up and walk out, nothing would be said, just up and out.

The next day Sister runs in and says, "the Bloody American fleet has just bloody well come bloody in. All the Nuns get up and walk without saying a word. Sister shouts back after them and says, "you don't have to bloody run they'll be here for a bloody week".
