Dick's Big Giant Headache (1) - S4-E23
Trivia: When the Solomons meet the Big Giant Head at the airport and ask how his flight was, he says that it was horrible because when he looked out the airplane window, he saw something on the wing of the plane. Dick responds that the same thing happened to him. William Shatner appeared in the 1960's Twilight Zone episode "Nightmare at 20,000 Feet" in which a gremlin tried to destroy the wing of a plane. John Lithgow appeared in "Twilight Zone: The Movie" playing the same character in the same situation.
Trivia: Steve Cardenas, who plays Rocky, did not make a personal appearance in this episode - only in morphed form.
Trivia: For some reason there is a picture of Batman's eye on Miss Parker's desk. It is between the picture of her and her father and a candy bowl. It looks like the Val Kilmer Batman, but I'm not sure. (00:00:25)
Trivia: When Kyle is knocked into the airfield by Siniestro, he crashes into a Sabre jet. As he recovers, we read the pilot's name as Col. Hal Jordan. This is the name of the second, Silver Age Green Lantern.
The Return of the Beast: Part 1 - S1-E1
Trivia: When we see the flashback of the accident that caused Bruce Banner to become the Hulk, at first we see the Hulk colored gray and then slowly turn green. This is a reference to the comics, in which the Hulk was gray in his original appearance.
