"What if I told you that Jebediah Springfield wasn't as great as he's cracked up to be?" Asked little 8 year old Lisa Simpson sitting in the kitchen where her mother (Marge) is making toast and her father (Homer) walked in his robe with a pirate hat on and ringing a bell.
"Look. Jebediah was really a vicious pirate named Hans Sprungfeld." She explained, "His tongue was bitten off by a Turk." "No tongue, eh?" questioned her father, "How did he talk and eat and laugh and love?" "He had a prosthetic tongue made out of silver." explained Lisa, pointing at a book she had with her father moving close to look at the diagram of the silver tongue.
"Yes. That'd do." Quipped Homer. "He was one of the evilest men of the 1780s. He ever tried to kill George Washington!" she said with Homer almost cursing and then imaging Sprungfeld attempting to kill Washington but failing.
"The next time Hans Sprungfeld was seen he had changed his name to Jebediah Springfield." Lisa explained as we return to the Simpsons kitchen where Homer has picked up the book and started looking though it. "Lisa, honey, when my family first came to this state they had a choice of living in Springfield or Stenchburg." Marge chimed in, "You know why they chose Springfield? "Because everyone knows Jebediah Springfield was a true American hero, end of story!" She yelled, she believed the lies just like everyone else in Springfield and was offended that Lisa would suggest otherwise.
She looks defeated but her father cheers her up when he tells her he believes her, "You're always right about this type of thing and for once, I want in on the ground floor." He said with Lisa thanking him before we cut to the school where Ms. Hoover is giving out grades.
"Ralph, 'A', Janey 'A', and Lisa for your…" She clears her throat and says "...essay, "Jebediah Springfield: Super Fraud," "F."" "But it's all true!" She explains but Hoover has none of it and tells her off with "This is nothing but dead-white-male bashing from a P.C. thug." She even adds "It's women like you who keep the rest of us from landing a husband." before she tosses on her desk.
We cut to Homer on the phone with someone finishing his conversation when he hears his little girl sobbing while walking upstairs and into her room, then she slams her door worrying Homer. He enters the room and hears her explained what happened at school. Homer then suggest they trash the place but Lisa brings him back to reality.
"No one's ever going to believe me." says Lisa, "But you have proof." He then suggests they could get the confession from Jebediah's fife. The two go to the Springfield History Society to confront Mr. Hurlbut about Jebediah Springfield. "Town Crier. I'd like to ask you a few questions. One: where's the fife, and two: give me the fife." He then takes the keys from Hurlbut's desk and goes to the fife which Hurlbut complains about but Homer tells him put this in his fife and smoke it.
He blows it and the confession hits Hurlbut in the forehead, Lisa tells him it's the confession and he takes it and reads it out loud. But he suddenly stops and says "Oh. I think, Lisa, that you've been taken in
by an obvious forgery." "Unfortunately, historical research is plagued by this sort of hoax-the so-called confession." He goes on about how phony it is, "It's just as phony as the Howard Hughes will, the Hitler diaries or the Emancipation Retraction." He throws it in the garbage with Lisa saying that it explains why there isn't any records of him before 1795 and who he truly was. But Hurlbut doesn't accept it and throws them out of the museum and banning them.
We cut to them in the car with Lisa saying, "I'm not going to give up. I refuse to believe that everyone refuses to believe the truth." They go to a print shop where they printout wanted posters of Jebediah Springfield and Homer and the Comic Book Guy have a confrontation about his screenplay. Lisa tries to put the poster up in the Kwik E. Mart but Apu takes it down, their next stop is Moe's bar.
"Hear ye, hear ye!" booms Homer opening the door to Moe's, he walks around in a circle saying "My daughter has something to tell you about Jebediah Springfield." "Aw! That little cutie wants to do something cute." Says Moe in an irregular mood before he quickly snaps back at the drunks sitting at the bar to shut up while Lisa prepares herself for what she's going to say. She holds up her wanted poster and announces to them all, "Jebediah Springfield was nothing more than an evil, bloodthirsty pirate, who hated this town." The drunks are in utter shock while Moe shouts oh my god, he leans on the counter signaling Homer and Lisa to come over. "Homer, you know I support uh, most any prejudice you can name but your hero-phobia sickens me." He then kicks them out of the bar and after they leave he calls up the Town Jubilation Committee alerting them of Lisa.
