The title refers to something that happens in the last minute of this cartoon, in Flip's Cafe. A customer is making noise slurping his soup so Flip puts music to his slurping. It's not well-received as the rest of the customers throw food at them!
This early animated effort gets off to a rousing start with some foot-tapping swing-type music in which we see the chimney of the building swaying to the music and fireflies acting as a neon sign, advertising "CAFE." That was pretty clever.
Inside, we get a some sight gags of how Flip runs the restaurant, some of the entertainment at the café - a hot female cat who flirts with Flip - and a whole bunch of music. There is no dialog. Overall, it's very dated but decent entertainment. The first segment of this cartoon was the best.
This was the second cartoon in a series of fourteen old ones on a DVD called "Cartoons That Time Forget: The UB Iwerks Collection Vol. 1."
