"Hank's Horny Halloween"
It's October 30th in Arlen, Texas, and our hero Hank Hill has been out of the hospital for several months since that time he fell into a coma (see Hank's Good Dream). He is now in his garage carving pumpkins for his Halloween porch. Then his wife Peggy comes into the garage and opened her mouth widely. "HANK!" yelled Peggy. "I told you that's not what you carve 'em with!" "And I told you Peggy, if my dick is sharp enough to carve jack-off-lanterns, then it's sure as hell sharp enough to stab your ass!" Then Hank turned his dick around when it suddenly exploded in Peggy's fully made-up face. "Oh shit," said Hank. "Sorry Peggy. That was supposed to be the candle wax."
"That's it Hank, I have had it with your shenanigans. You are gonna put your clothes on, go outside, and you're gonna fetch Bobby a new trick-or-treating costume. He is too big to wear the one from last year." "What're you talking about Peggy? He looks just like David Bowie." Then we cut to his son Bobby dressed up as David Bowie, and also looks like Jabba the Hutt from Star Wars. And now back to Hank. "Okay fine" he said. "Let's get you some new digs, Bobby."
After the two of them changed, Hank and Bobby leave home in the red truck. And on the way there, Bobby stuck his head out the window and got hit with a stop sign. That didn't hurt him because his gelatinous fat made him immune to pain. On closer inspection, the sign turned out to belong to the one and only JACK BLACK! But they couldn't find him so they just kept driving.
Now the two of them made it to Mega-Lo-Mart, and they're having a sale on all the Halloween shit; candies, costumes, and jack-off-lanterns of course. Hank tries to find a suitable outfit for Bobby this year, but they're all cringy get-ups instead of anything scary at all. "Let's see what we have here: a pumpkin, big green ogre, 5 Nights at Babby's, Spinglebab…" And then Hank comes across an outfit that he thought was too scary. "BWAAAAAAAAAH! SPOOKY SCARY SKELETON! …Oh it's only a Sans costume, Bobby. Nothing to be afraid of."
Finally, Hank saw something that was beyond expectations. "Holy crap Bobby, I've got it!" He then pointed to a slutty nun costume, and had him change into it. "Will it make me look purdy?" asked Bobby. "Yes it would," said Hank as he grew bedroom eyes and squeezed Bobby's butt, "Halloween purdy."
The two of them head to a checkout line, with Bobby slithering in his new sexy nun costume. But this cashier named Tate is standing there, and he doesn't like what he sees. "I'm sorry sir," said Tate. "Your blob's gonna have to put that costume back." "Blobby's gonna wear this costume and YOU'RE gonna like it!" said Hank with a stern face. "Alright, alright," said Tate, "I'll make it free." "You will?" "Sure, with the purchase of My Little Pony: the Movie on Blu-ray." "You fucking bastard." Even though Hank despised the offer, he purchased the movie and the costume that comes with it, and took Bobby home. And they still never found Jack Black.
