I saw a cartoon in the late-'60 or early-‘70s. I don’t remember if it was colour or black-and-white. I don’t know the era it came from. I don’t know the main character of the cartoon. I don’t know which studio’s style it was. The character might have been a duck, and it may or may not have been Daffy Duck. Or he may not have been a duck at all. So basically… I got nuthin’.
IIRC, the deranged character was motivating in a circle. Or a straight line. He kept singing ♫ We’re shovin’ right off agiiiiiin ♫ We’re shovin’ right off agiiiiiin ♫ We’re shovin’ right off agiiiiiin… ♫
