After being inspired by a cartoonist during Career Day at Springfield Elementary, Bart creates an Internet cartoon based on Homer's anger problems called ''WebAnimation/AngryDad''. Meanwhile, the Comic Book Guy has his hands full when Marvel Comics man Creator/StanLee begins harassing him and scaring off his customers.

!!Tropes:
* AdamWesting: Creator/StanLee voices a deranged version of himself.
-->"He can't be the Hulk! I'm the Hulk!"
* AuthorAvatar: Bart creates a cartoon about his father, just like Creator/MattGroening based the Simpsons on his own family.
* BitingTheHandHumor, InkSuitActor, and TakeThat: Bart's voice actor for the Angry Dad Internet cartoons is based on Creator/DanCastellaneta (the voice actor best known for playing Homer Simpson), who gets the job for capturing the spirit of Angry Dad ("Whoo-hoo! When do I get paid?"), but won't be paid until 2012 ("D'oh!")
* BodyHorror: When trying to suppress his anger, boils keep popping out of Homer's neck until a whole bunch of them spring up.
* BreadEggsMilkSquick
-->'''Homer''': I gave up anger forever. From now on, I'm into candles, soft music, and horse tranquilizer.
* BuffySpeak: "I'm a rageaholic, and I can't live without Rageahol!"
* CallBack: When Homer is suppressing his anger, he starts "diddly"-ing, [[Recap/TheSimpsonsS8E8HurricaneNeddy just like Flanders]].
** Also, when watching an episode of ''[[ShowWithinAShow When Dinosaurs Get Drunk]]'' where a Stegosaurus wanders into a tar pit, he chuckles and says that [[Recap/TheSimpsonsS5E17BartsGetsAnElephant he's been there.]]
* CheekCopy: One of the employees at betterthantv.com is seen the background Xeroxing his butt.
* {{Cloudcuckoolander}} and {{Troll}}: Creator/StanLee is portrayed as both of these.
* CompositeCharacter: Parodied. Bart claims Angry Dad to be a mix of three dads: his dad, Lisa's dad and Maggie's dad.
* HairTriggerTemper: Homer's anger problems inspire Bart to create Angry Dad.
* HulkingOut: "HOMER MAD! HOMER SMASH! GET REVENGE ON WORLD!"
** Stan Lee tries to transform into the Hulk, claiming to have actually done it in the past.

'''Comic Book Guy:''' Oh, puh-leese! You couldn't even turn into Bill Bixby!\\
'''Stan Lee:''' Mmmmm! Aw, forget it. Mm-mmmm! I really did it once!\\
'''Comic Book Guy:''' ''[walking Stan Lee in the store]'' Yes, yes. I just wish you had the power to leave my store.\\

'''Comic Book Guy:''' You almost had it there.
* HalfwayPlotSwitch: This is an episode that tries to pretends its about comic books when its actually about flash videos.

* MagicPants: Worn by Homer Mad and [[LampshadeHanging lampshaded]] by Bart.
* NoodleIncident: Stan Lee apparently turned into the Hulk once.
* NonIndicativeName: ''The Danger Dog Easter Special'' has nothing to do with Easter.
* OffModel: {{Lampshaded}} by Comic Book Guy who calls the ''Angry Dad'' character this in every frame, but still considers it worthy of being sold in his store.
* RageBreakingPoint: Homer finally lets his surpressed anger loose when he falls into a kiddie pool filled with green paint.
* RealityEnsues: Homer doesn't really [[HulkingOut Hulk Out]], he just gets ''really'' angry. And despite that, he's still easily subdued by the police.
* ShoutOut: Bart's latest attempt to drive Homer furious involved green paint and made Homer look like ComicBook/{{Hulk}}.
* ShowWithinAShow: ''Angry Dad'', ''When Dinosaurs Get Drunk'' and ''Danger Dog''.
* StalkerWithACrush: The Comic Book Guy is this towards Lynda Carter:
--> The restraining order says "no-no", but her eyes say "yes-yes".
* TakeThat: To the popular dot.com bubble burst of the late 90s-early 2000s.
** Apparently, Danger Dog's mortal enemy is [[Creator/MollyRingwald Molly Ring]]''[[Creator/MollyRingwald worm]]''.
* TheInternetIsForPorn: ''Angry Dad'' is ranked #1, excluding porn. Including porn, it's #10,000,000,000,000.
