The first five Fun fact comics came out over a span of more than six years, with more than three months between the two closest to each other, but the next two, 1950: Chicken Pox and Name Statistics and 1959: The Simpsons, came out just three weeks apart, with only 8 comics between them, in February 2018, after a break of more than two years since the previous one, 1609: Food Combinations in November 2015.

This could also be the reason he returned to his problems with Small Talk, a subject he had last used three times in a row exactly two years ago, in the next comic, 1961: Interaction.
Below is a list of the comics that uses "Fun facts".
