Alternative Character Interpretation: Lt. Gadget is a Jerk Ass robotic double of the original Gadget and hides behind a facade of Obfuscating Stupidity in order to get away with all the damage he causes and keep people from finding out the truth. Seriously, just watch the way he acts after every time he causes Nozzaire grief.
Fridge Brilliance: Sometimes the Gadgetinis call Penny "mom." Technically, she is their mother.
Ho Yay: Gadget and Nozzaire almost have a Squidward-Spongebob dynamic going on, with Nozzaire constantly hating and fearing Gadget to the point of obsession due to constantly being maimed by his gadgets and Gadget friendly and eager to please towards Nozzaire while being oblivious to his hatred and trying to ignore the constant pain he inflicts on Nozzaire.
Jerkass Woobie: Nozzaire. You will feel sorry for him whenever Gadget puts him through hell, but at the same time he's an egotisticial jerk with few redeeming qualities.
Nightmare Fuel: In one episode, M.A.D. Agent Dr. Wacko makes a clone of himself. After arguing with the clone for a bit, he uses his control and tells the clone to go back to the chamber and disintegrate himself. He basically told his clone to COMMIT SUICIDE.
