Dirty Gandalf

To add extra credibility to the act, midgets dressed as Hobbits may be used as well as other props like robes, staff etc. Photographs must me taken for posterity.

Darling , I have ordered midgets for tonight, get your robe on, its time for Dirty Gandalf to arrive.

Gandalf the Brown 

The first solid poo to make an appearance after a long hard fought with diarrhea, signalling that the tide has turned.

In 'The Lord of the Rings: The Two Towers', the Battle of Helms Deep is all but lost until Gandalf the White appears, handing victory to the men of Rohan against the Uruks of Isengard.

Similarly, the arrival of Gandalf the Brown reveals that the battle for control of your bowels has been concluded in your favour.

Guy 1: You coming swimming later?

Guy 2: I can't, I have a bad stomach, I need to rest.

*30 minutes later*

Guy 2: I'll be coming after all, Gandalf the Brown has arrived.
