I remember reading here on HN of some web or ad agency intentionally adding a duck to a page before a demo to the customer. The customer eventually said, it's all OK but please remove the duck. They directed the customer's need to fix something to an obvious target. The customer is happy to have made a difference, the agency is happy not to have to do some extra work on something expensive to fix.

One origin of that approach is from Battle Chess - aka a duck feature: https://blog.codinghorror.com/new-programming-jargon/.
