Toonfomercial: Dinty Moore, the singing lumberjack (1973)

 Dinty Moore beef stew has been one of Hormel's longest running products, such that it's included in the company's line of microwave meals.

Back in 1973, someone came up with the idea of creating a Dinty Moore character to sell the product, a singing lumberjack serving his namesake stew to a hungry worker, the idea being that it's "dinner for lunch". Check it.
