This episode sees a change in the font used for the on screen credits played over the beginning of the episode and end credits. The end credits now also credit each guest star with the character they played rather than just a select few, and the copyright date at the end is now shown in Roman Numeral rather than a numerical date.
The title is from a line in "To a Mouse" by Robert Burns: "The best laid schemes o' mice an' men / Gang aft a-gley."
