Why do so many of the best and most original Looney Tunes shorts seem to feature Daffy Duck?

In today’s Toons & Tunes, the little black duck dons the voice of the Velvet Fog, Mel Torme, and croons lounge singer style to a club full of monsters, informing us that “Monsters Lead Such Interesting Lives”, a phrase originally coined by Bugs Bunny in “Hair-Raising Hare”. Enjoy “Night of the Living Duck”.
