Dialogue Edit

The Sleuthenizer Pt. 1 Edit

Start Edit

Character Dialogue
Comic Book Guy Icon Interesting. Various characters are reverse-aging into babies, much as in classic Futurama episode 4ACV09.
Comic Book Guy Icon Although in that story the device was called a "Youth-a-sizer", not a "Youthenizer", so this is very, very different.
Lisa Annoyed Icon Instead of nitpicking sarcastically, why don't you help for once?
Bart Icon Yeah! Like, tell us how superheroes would un-reverse the aging process.
Comic Book Guy Icon Well, let's see. In the movie Superman, the hero of the same name reversed Earth's rotation, causing time to run backwards.
Comic Book Guy Annoyed Icon However, that's the third stupidest thing in history, behind two things Aquaman did that are too embarrassing to discuss.

The Sleuthenizer Pt. 2 Edit

Start Edit

Character Dialogue
Lisa Icon I should have come to you first, Professor Frink. Can you reverse the Youthenizer?
Professor Frink Icon Hmm. I once un-reversed an Oldening Ray, so the process should be similar. Stand back while I bloink the gizmodulator...
Youthenizer Icon  BEGIN YOUTHENIZATION YET AGAIN
Bart Surprised Icon Oh no! Not yet again!
Baby Frink Surprised Icon Good glayvin, I'm a baby now? I've never seen a Youthenizer on such a hair trigger!
Lisa Embarrassed Icon Y'know, I'm just going to hide it behind a napkin to avoid any more accidents.
Baby Frink Happy Icon That's all well and good, but I've lost my object permanence. So since I can't see it, it doesn't exist! Problem solved!

The Sleuthenizer Pt. 3 Edit

Start Edit

Character Dialogue
Lisa Sad Icon *sigh* Everyone who tries to help just ends up in a soiled onesie of their own making. I've got no one left to turn to!
Bleeding Gums Murphy Cloudy Icon Lisa, believe in yourself! Stop listening to smart people, and for no reason start listening to clouds that resemble deceased saxophonists.
Lisa Icon That is offensively stupid, pseudo-religious bunk! And it makes me feel better! Thanks to you, the clouds are beginning to lift.
Lisa Icon Hey, why are you lifting? Goodbyyyye!

The Sleuthenizer Pt. 4 Edit

Start Edit

Character Dialogue
Lisa Playsax Icon I find I often get ideas when I'm playing the saxophone.
Bart Sneaky Icon That gives me an idea! Let's go ride our bikes so I don't have to listen to you play the saxophone.
Lisa Icon Okay. We're on our bikes now.
Bart Icon Yep. And we're riding past the teen center.
Lisa Happy Icon Wow! We're suddenly covering a lot of ground, both on our bikes and in the plot.
Bart Icon Say Lis... teenagers are good with technology, right? Maybe that dork over there can help with the Youthenizer.
Teenage Smithers Icon Who, me?
Lisa Shocked Icon *gasp* Mr. Smithers?! You're a teenager now?!
Teenage Smithers Sad Icon Ugh, don't ask. I got a partial blast from a hair-trigger, ivory-block Youthenizer. But you kids wouldn't know about that.

The Sleuthenizer Pt. 5 Edit

Start Edit

Character Dialogue
Lisa Sad Icon We need your help, Mr. Smithers.
Teenage Smithers Icon Please, don't call me "mister".
Bart Icon Oh, right, on account of your confused sexuality.
Teenage Smithers Surprised Icon Say what? As a teenager, I'm simply not accustomed to being called "mister".
Teenage Smithers Icon Although come to think of it...
Lisa Icon Later! Right now we need to reverse the Youthenizer. It's here, in my bike basket.
Lisa Icon No, wait, that's my smart speaker. It's over in Bart's basket.
Teenage Smithers Icon Be careful with that! Mr. Burns was using it last week. I tried to run, but a glancing wave caught the edge of my left adenoid and made me a teenager.
Lisa Surprised Icon So Mr. Burns is behind this! I knew it all along!
Bart Curious Icon You did? Then why are you conducting a painstaking investigation?
Lisa Icon It's how I do.
Lisa Happy Icon Now let's put some music on the smart speaker and head for the power plant!
Youthenizer Icon BEGIN YOUTHENIZATION FOR NOT THE LAST TIME
Bart Surprised Icon Lisa! You've been baby-ized!
Baby Lisa Surprised Icon Oh God, this is terrible! I won't be able to play the saxophone again for years!
Bart Happy Icon Hooray!
