First Pink Panther episode "Pink Phink" airs 1964

The first Pink Panther episode, Pink Phink, aired December 18, 1964.  The animated short would win Best Animated Short at the 37th Academy Awards.

It features the Pink Panther and a painter known as "Little Man" battling for the color of a house.  Little Man wants it blue, but the Pink Panther undoes his hard work by re-painting everything pink.  

The studio DePatie-Freleng Enterprises is the first studio to win the award for their first short. Pink Phink is the only short from the studio that won any Academy Awards. The Pink Panther shorts used the music from Henry Mancini's Academy Award nominated soundtrack to the Pink Panther movie series staring Peter Sellers.

I could only find the short film in color without sound, or without color with sound.  I preferred to hear what was going on, so here it is.
