Shouldn't there be some kind of relationship between how much a baby eats and how much comes out the other end? It's like at the circus, where they've got the tiny VW bug but the clowns just keep coming out and out and out. . . . Eventually you learn how to hold your breath like a Hokkaido pearl diver.

In this stand-up style riff, Miller uses exaggerated analogy to capture a common new-parent shock: the seeming mismatch between an infant’s tiny intake and the relentless output of diapers. The circus image (endless clowns emerging from a small car) turns a mundane bodily reality into a comic spectacle, emphasizing surprise and disbelief. The closing reference to “holding your breath like a Hokkaido pearl diver” adds a second layer—parenthood as an acquired endurance skill—suggesting that caretaking involves adapting to unpleasant, repetitive tasks until they become routine. The humor depends on escalation, vivid imagery, and the cultural shorthand of endurance divers.
