A Jester would fit in perfectly with the mood of our Eberron game (on Google+). Thus far the party has hunted a Turducken, defeated the broken rocky remains of a Stone Giant lying in pieces across a streambed, overcome a giant cuckoo clock which attacked them with its dangerously sharp pendulum and shot at them with its clock-hands, and escorted a troupe of dancing (and talking) bears into Zilargo.
