Herman the Catoonist (1953)
Animation
When the cartoonist takes a coffee break and leaves the office for a spell, Katnip and "Hoiman" break the 4th-dimesion wall (and several dozen real walls)with their escapades and conflicts and ideas exchanges. Katnip, per usual, gets the short end as Herman leaves him stuck in the ink bottle.
