[I'm sorry I have no video editing or voice acting skills to make the following script into a reality.]

TJ "Henry" Yoshi: Well, Pannenkoek, I made it, despite your directions.

Pannenkoek: Ah, TJ "Henry" Yoshi, if that is your real name. I hope you're ready for an unforgettable Watch for Rolling Rocks.

TJ "Henry" Yoshi: Eh.

[Pannenkoek enters Hazy Maze Cave and sees that he has to press A]

Pannenkoek: Ye gods, my low-A-press run is ruined! Hmm. . . But what if I were to hold A from a previous level? Ho ho ho ho! Delightfully devilish, Pannenkoek! *begins to press A*

[TJ "Henry" Yoshi enters]

TJ "Henry" Yoshi: Ah. . .

[Musical number]
Pannenkoek with his crazy explanations. TJ "Henry" is gonna need his medication, when he hears Pannenkoek's crazy explanations. There'll be trouble in SM64 tonight!
TJ "Henry" Yoshi: PANNENKOEK!!!

Pannenkoek: TJ "Henry" Yoshi! I was just transporting this scuttlebug! Every time it hits you its home resets to a new location! Care to join me?

TJ "Henry" Yoshi: Why are you pressing A, Pannenkoek?

Pannenkoek: Oh! That's not an A press! Those are B presses! Mmmm, B presses!

TJ "Henry" Yoshi: Eh. [Exits.]

Pannenkoek: Phew. [builds up speed for 9 hours]

[Pannenkoek enters the dining room]

Pannenkoek: TJ "Henry" Yoshi. I hope you're ready for holding down the A button!

TJ "Henry" Yoshi: I thought you said you were going to press the B button.

Pannenkoek: No I said "half A press." That's what I call holding the A button down from a previous level.

TJ "Henry" Yoshi: An A press is an A press. You can't say it's only half.

Pannenkoek: Yes I can. An A press has three parts.

TJ "Henry" Yoshi: Uh huh. What parts?

Pannenkoek: Pressing the button, holding it down, and releasing it.

TJ "Henry" Yoshi: Really. Well I've speedran any% SM64 and I've never heard anyone use the phrase "half A press."

Pannenkoek: Oh, not in an any% run, no. It's a low-A-press run expression.

TJ "Henry" Yoshi: I see.

TJ "Henry" Yoshi: You know, you'd still have to press A at some point in order to be holding A during Watch for Rolling Rocks, so that'd count as an A press.

Pannenkoek: Oh ho ho ho, no. You can hold A from a previous A press that you used for a different level. Old Pannenkoek strat.

TJ "Henry" Yoshi: For a "half A press."

Pannenkoek: Yes.

TJ "Henry" Yoshi: And you call it that despite the fact that you have obviously fully pressed A.

Pannenkoek: Well. . . you know. . . One thing I should-. . . excuse me for one second.

TJ "Henry" Yoshi: Of course.

[Pannenkoek uses his built up speed to zoom around Hazy Maze Cave]

Pannenkoek: [yawns] Ah, well, got the star. A good time was had by all. I'm pooped.

TJ "Henry" Yoshi: Yes, I should- Good lord, what is happening in there!?

Pannenkoek: Parallel universes.

TJ "Henry" Yoshi: Eh!? Parallel universes!? In this game? In this part of the castle? Almost twenty years after SM64's release? Localized entirely within Hazy Maze Cave?

Pannenkoek: Yes.

TJ "Henry" Yoshi: May I see them?

Pannenkoek: That would crash the game.

[TJ "Henry" Yoshi exits]

Pannenkoek's mother: [yelling from upstairs] Pannenkoek! I'm trapped in a parallel universe!

Pannenkoek: [calling up to his mother] No, mother! You just have to be QPU-aligned!

TJ "Henry" Yoshi: Well, Pannenkoek, you are an odd fellow, but I must say. . . you half-press a good A button.

Pannenkoek's mother: Help! Help!

[Pannenkoek smiles and gives a thumbs up]
