Blondie Knows Best (1946)

Dagwood Thinks He Has All The Answers... But Blondie Knows Best!

Dagwood Bumstead poses as his boss Mr. Dithers so that a big business deal can be consummated while Dithers avoids nearsighted process server Jim Gray. The upshot of all this is that Dagwood ends up in a lunatic asylum, forcing Blondie to come to the rescue.
