Comedy routines make a great big deal of husbands not paying attention to anything that their wives say. It’s often just done for effect, but there are definitely plenty of occasions where a woman will give very simple instructions to her husband and he’s not paying attention, because there’s a football game on TV or the cat has just jumped at its own fart.
This is probably one of those cases. “Honey, we need a new leg for the flamingo in the garden, can you order one? It’s about 30cm.” What the husband heard: “we need a new leg for the flamingo, blah, blah, blah.” Then he turns around and orders the first thing he sees on Amazon, which just happens to be a 30-foot pole. I can’t imagine why his wife was annoyed.
