[Cut to the Magic School Bus driving past a sign reading "The Grand Canyon"]
Male chorus (singing): On the Magic School Bus!
[We cut to inside the Magic School Bus]
Ms. Frizzle: Here it is, kids! The Grand Canyon!
[All the kids except Arnold cheer]
Arnold: Ms. Frizz, you said we were going to the natural history museum!
[All the kids are dismayed]
Ms. Frizzle: Magic school buses don't do standard curriculums.
Arnold: Ms. Frizzle is batshit crazy! Does she even have a teaching degree?
Ms. Frizzle: It's honorary. Seatbelts, on kids!
[The kids start putting on their seatbelts]
Arnold: No one else was already wearing a seatbelt!
[Ms Frizzle pushes down the gas and the bus accelerates quickly towards a cliff edge]
Arnold: Hey, we're...running out of road!
Ms. Frizzle: Where the road ends, adventure begins!
[Ms. Frizzle drives the Magic School Bus off the edge and down the cliff as all the kids except Arnold cheer again]
Ms. Frizzle: Okay, bus, do your stuff!
[The bus crashes at the bottom of the cliff, killing everyone on it. After a while, the Magic School Bus floats up again, now wearing angel wings, we cut back to inside the bus, where everyone wears angel halos]
Ms. Frizzle: See, Arnold? Adventure awaits in heaven!
[Ralphie walks over to Arnold]
Ralphie: Yeah, see, Arnold? You pussy!
[Cut to the bus flying up into the sky to heaven]
Male chorus [singing]: The Magic School Bus!
[Cut to static]
