I think all the titles in the whole series are inside jokes for something else.
For instance:
In season 1--All Shook Up is the title of an Elvis song, Vatman was used in the synopsis for Superman IV, Fly Hard is a play off of Die Hard, etc.
Then in season 2--Season's Greedings plays off of Greetings, The Eyes Have It could have been "The I's have it," and Tempus Fugitive=Tempus Fugit or "Time Flies."
Season 3--Just Say Noah ("Just say no"), Chip off the Old Clark ("Chip off the Old Block"), and Double Jeopardy is a double-entendre.
In season 4 you have Lord of the Flys ("Lord of the Flies"--which I read in 11th grade), 'Twas the Night Before Myxymas ("'Twas the Night Before Christmas"), and Toy Story.
