Looney Tunes "Now Hear This" Opening and Closing 

Released:April 27, 1963
Director:Chuck Jones
It is notable for being the first short using a theme sequence without the trademark orange Color Rings.
This intro sequence would later used on Bartholomew Versus the Wheel and Señorella and the Glass Huarache in 1964.
This short was nominated for an Academy Award, and was the last Looney Tunes short to receive an Academy Award nomination.

(One of my favorite.)
