Just make a completely wild and inaccurate prediction loosely based on fake polling data, and then graph it. Like they did when they predicted Trump had only a 1% chance of becoming president.
In the weeks leading up to the election, they were putting Trump's odds at 1/4, and pretty roundly mocking/cautioning against others who were putting him at 1%. On mobile, so I can't check by hovering, but I don't think they ever put his chances below 1/10: https://projects.fivethirtyeight.com/2016-election-forecast/
Yeah, of all the groups making predictions they gave Trump the highest odds of winning [0].
