When it comes to the cartoons produced under Seymour Kneitel's reign at Paramount's animation studio, the best were either the Irv Spector-penned cartoons or Swifty and Shorty, created and voiced by comedian Eddie Lawrence (aka "The Old Philosopher"). The funny voice acting and clever writing made the series stand out from others, and it's a darn shame that its so obscure.
12 shorts were made under Kneitel, all released in 1964; Howard Post made four more in the following year. By then Lawrence had stopped doing the voices and was replaced by Bradley Bolke and Jack Mercer, voicing Swifty and Shorty respectively.
These two are from Post's reign. (Click here for the Kneitel/Lawrence short)
Ocean Bruise (1965)
This one has some similarities to the Gene Deitch Tom and Jerry short Dickie Moe. Not much of a coincidence, since both cartoons are written by Eli Bauer.
Getting Ahead (1965)
