The significance of raising the turkey from the dead?

I've always wondered why, exactly, does casting "raise dead" on the turkey serve as the catalyst for moving the adventure along? You know, the part where they're sitting around the campfire with the mask and everyone but Daphne (and Osric, secretly) thinks the adventure is over. Was it just a random funny thing, and Daphne's questions were the catalyst? Or did raising the turkey somehow have a point?
