Latest comic
| Messi |
 Title text: Commentators agree that this will probably be the last World Cup in which Messi faces serious competition. |
Explanation
In the vein of 605: Extrapolating, this comic utilizes the incorrect application of extrapolation to humorous ends. Extrapolation is a form of estimation in which existing data points are used to estimate new data points beyond the range of the existing ones. In this case, Randall appears to have fit several data points regarding soccer superstar Lionel Messi's average goals per World Cup game to a curve using what appears to be polynomial or exponential extrapolation. It illustrates the danger of a small sample size, as the data point for "2026 (so far)" is based on only one game (the day before this comic, in his inaugural game of the 2026 World Cup, Messi scored three goals), and that data point is used to support extrapolation of a rapidly rising number of goals-per-game into the future. The data points for previous World Cups, which bounce around among various values but are all less than or equal to 1.0, are each based on many more games, and as such are likely to be much better estimates of how many goals-per-game Messi will score in the future.
The title text says that this World Cup is the last one in which Messi will face serious competition. This is likely true, but humorously so, as this is almost certainly Messi's last World Cup period.
