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 StanLee begins harassing him and scaring off his customers.

!!Tropes:
* AdamWesting: StanLee voices a deranged version of himself.
-->"He can't be the Hulk! I'm the Hulk!"
* 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!")
* {{Cloudcuckoolander}} and {{Troll}}: 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!"
* KickTheDog: Homer randomly starts punching Snowball II and wasn't even aware of it until Marge pointed it out.
* ShoutOut: Bart's latest attempt to drive Homer furious involved green paint and made Homer look like {{Hulk}}.
* ShowWithinAShow: ''Angry Dad''.
* TheThingThatWouldNotLeave: Stan Lee doesn't seem to leave the comic book store.
-->'''Bart:''' Stan Lee came back?
-->'''Comic Book Guy:''' Stan Lee never left.
