Randall spoofs this idea. In the comic, [[Cueball]], as a [[:Category:News anchor|news anchor]], presents a heading which opens his story by asking if millennials are killing the industry of surgical {{w|Joint replacement|joint replacements}}, illustrating it with numbers of joint replacement procedures among millennials compared to baby boomers. The joke is that millennials are simply too young for most of them to need joint replacements (which are usually used to treat senile {{w|osteoarthritis}}), so most people will see that so there really isn't a news story here. Randall is using this example to highlight that this kind of story is ridiculous. Millennials will likely need joint replacements in the future as they get older, potentially keeping sales of joint replacements at close to their current rate. | Randall spoofs this idea.

| − | A '''{{w|cohort effect}}''' is a cultural difference between generations (such as buying fewer diamonds), whereas an '''age effect''' is one that is simply related to getting older (such as getting arthritis). Joint replacement rates are an age effect, but the newscast is presenting them as if they were a cohort effect.

The title text points out that although numbers of millennials receiving joint replacements are low, they are higher than the numbers of baby boomers who received them ''at the same age''—i.e. in their 20s—due to advances in medical diagnosis and technology in the last 50 years, as well as (in some countries at least) better access to healthcare. This statistic can be used to create a headline which is the reverse of the one in the comic, namely "millennials are getting more joint replacements than ever". Randall notes that you could therefore use either headline to back up your argument, depending on the agenda you are trying to present. | The title text points out that although numbers of millennials receiving joint replacements are low, they are higher than the numbers of baby boomers who received them ''at the same age''—i.e. in their 20s—due to advances in medical diagnosis and technology in the last 50 years, as well as (in some countries at least) better access to healthcare.
