I found a compass online (the one where you can change the direction of the arrows printed on paper) and was wondering if anyone actually uses it, and what their patter was.

Thanks

A good patter theme I've seen is you're in a department store, trying to follow the signs to the men's department or to make a return, and you keep ending up in the wrong department. This may give you some ideas.

How about this? Scientists say that magnetic north is shifting faster than expected (this is true -- look it up), and so magnetic compasses aren't so reliable anymore. Well, I have here a non-magnetic compass. As long as the arrows on both sides are pointing in the same direction, you're headed right. Take it from there.
