Category:Substitution

Substituting one word with another has become a recurring subject on xkcd. After the first four comics using substitutions as part of the joke, Randall posted the first comic of the Substitution series, 1288: Substitutions, listing a set of substitutions "that will make reading the news more fun". He later released two more comics with the same caption, distinguishing the Substitution series from the other general substitution comics.
