Goof The name of the alter ego of Saturn Girl is misspelled in the credits. It should be Imra, not Irma.
This episode is one of two episodes in which Clark Kent/Kal-El does not actually appear as Superman. The other is "The Last Son of Krypton (1)," which focuses exclusively on Jor-El.
Chameleon Boy: Aw, just when we were getting to be buds.
Cosmic Boy:It's not right for a person to know his own future.
Saturn Girl: Yes, he needs to find his own way.
Chameleon Boy: Up, up, and away! I always wanted to say that.
Clark (looking for a disguise): Like a pair of glasses is gonna fool anybody.
Scientist: This is crazy!
Chameleon Boy: You asked for heroes, you didn't say anything about sanity.
Lana Lang: What's this strange power you have?
Clark: What do you mean?
Lana Lang: The ability to attract every airhead in Smallville.
Lightning Lad's exclusion in favor of Chameleon Boy was probably due to the fact that at the time of the show's production, (the early 90') the character was known as Live Wire, and would have been confused with the Villainess of the same name.
The Legion of Super-Heroes made their first appearance in Adventure Comics #247 (April 1958), which took place during Superman's teenage years as a superhero, Pre-Crisis. The three Legionnaires (Lightning Lad instead of Chameleon Boy seen here) came from the future to offer Superboy membership in the Legion out of respect for the legend of Superman, and Superboy traveled back and forth to the future to assist the Legion on many occasions. Post-Crisis, Clark Kent was never Superboy in the comics, although his teenage clone, Conner Kent, did join. After Infinite Crisis, continuity was rewritten again, and now Clark Kent was a member of the Legion as Superboy.
Lana Lang appears in this episode.
Martha makes the comment, "Jonathan, aren't The Dukes of Hazzard on now?" On the TV show Smallville, the actor that plays Jonathan Kent also played Bo Duke from The Dukes of Hazzard. This is especially interesting since this episode aired several years before Smallville premiered.
Chameleon Boy: Up, up, and away!
Up, up, and away is a quote that was often said by Superman in early appearances before taking flight and is also the title of a Superman comic book series that ran in 2006.
Clark Kent: Kareem here says he can burn my butt.
Reference to the basketball hall of famer Kareem Abdul-Jabbar.
Jonathan Kent: You almost gave me a heart attack!
In the 1978 film Superman and in most comic continuities, Jonathan Kent dies of a heart attack when Clark is a teenager. This line is likely a reference to that.
Lana Lang: You are so weird.
Lana's comment to Clark when she sees him trying on the glasses almost exactly echoes Lois Lane's (Teri Hatcher's) comment to Clark (Dean Cain) in the pilot of Lois & Clark: The New Adventures of Superman when she said, "You are so weird. Works for you, though."
