Ha. Like you would actually keep a deal with a bunch of rats. You pick up one of the cheese wheels and start a bloody squeaking massacre.
Finally, there is one rat left. You walk over to it with the gory cheese wheel raises for a fatal blow when it starts to speak.
"Wait! I'm not a rat! I'm really a minor Count from Bosnia. If you spare my life I will show you where the witch is and we both can get justice!"
