The use of the word "ain't" in the phrase "ain't I" is humorous because it is similar to the taboo word "fuck". The Globe and Mail of Toronto editorialized: "a dictionary's embrace of the word 'ain't' will comfort the ignorant, confer approval upon the mediocre, and subtly imply that proper English is the tool of only the snob".
