Sellers 4: chin-nick-key-key-key

continuing on

The animated Pink Panther character's initial appearance in the live action film's title sequence, directed by Friz Freleng, was such a success with audiences and United Artists that the studio signed Freleng and his DePatie-Freleng Enterprises studio to a multi-year contract for a series of Pink Panther theatrical cartoon shorts. 

Note from the DePatie-Freleng Enterprises wiki page:

Founder	David H. DePatie Friz Freleng

• David Hudson DePatie (born May 26, 1935) 
• Isadore "Friz" Freleng (August 21, 1906^[2] – May 26, 1995)

Freleng died on DePatie's birthday!!  

1977[edit]

Title	Date	Director	Synopsis	Notes
Therapeutic Pink	April 1, 1977	Gerry Chiniquy	The Pink Panther tries to get a dog removed from his tail at the hospital.	Final theatrical Pink Panther entry; last entry to utilize both Walter Greene and William Lava's music scores.

Note the "Greene"... another addition to the "Christmas Theme" pattern-cluster.  

• Walter Greene (January 23, 1910 – December 23, 1983) 
• Germain Adolph "Gerry" Chiniquy (pronounced "CHIN-nick-ee") (June 23, 1912 – November 22, 1989) 
• William "Bill" B. Lava (March 18, 1911 – February 20, 1971)

Hmm Chiniquy's pronunciation, chinnickee reminds me of chickadee... a christmas kind of bird.  So... a chinnikee's song would be "chin-nick kee kee kee... or is that "chin-nick-key-key-key"!! Think about it: chin nick (cleft chin) is the key-- evidence of our inner/conjoined twin... we are joined latterally ... like the Hensel conjoined twins excerpt that our heads are joined in like manner to the rest of their body-- still two heads, butt near perfectly conjoined... save for the little jolly "nick in the chin".
We now have a "December 23, January 23, __, __, __, __, June 23.../ 23rd Day, Month Sequence" pattern-cluster. Audd, we have Lava... how does that fit in with Christmas?!
