A 1945 Warner Bothers cartoon directed by Creator/BobClampett and written by Warren Foster. The cartoon features Daffy Duck and Porky Pig placed in charged of a stork factory delivering babies, where things tend to go as they [[HilarityEnsues usually do]].
It's placed as #4 in Literature/The100GreatestLooneyTunes.
!!''Baby Bottleneck'' provide examples of the following tropes:
* AppleOfDiscord: The egg.
* BunglingInventor: The dog that tries to pitch his detonating rocket transport to Porky.
* TheCameo: Tweety Bird is seen on the belt.
* DerangedAnimation: The entire short is crazy with it's animation, but the conveyor belt sequence ''especially'' stands out.
* DeliveryStork: In this case the storks get overworked and can't make any deliveries.
* NoOSHACompliance: The conveyor belt doesn't look really safe for babies, and it will diaper just about anyone in it.
* OffModel: The cartoon actually has a significant level of errors or oddities compared to standard ''LooneyTunes'' shorts, clothing disappears and reappears, elements are colored improperly, in cases such as the above shot, they don't even bother to draw a background. It tends to be treated more leniently by animation buffs since the animation itself is exceptionally fluid and entertaining.
* PackedHero: Daffy and Porky get stuffed in a single diaper, Daffy being the upper part, and Porky as the lower part.
