What is a celebrity cipher puzzle?

A celebrity cipher puzzle is a specific type of cryptogram published in a variety of print news outlets. The primary difference that sets this particular puzzle apart from other cryptograms is that it uses quotes from well-known individuals, both past and present, as its puzzle solutions.

A cryptogram is a piece of text that has been encrypted using a substitution cipher, wherein each letter in the original text is replaced by that of another one in the alphabet. Each replaced letter is consistent throughout the entire cryptogram, and the arrangement of words and punctuation remain the same as the text before encryption.
