Pinkie Pie and Mikey are invited to Cheese Sandwich’s gag factory. So they head out, wanting to know what their life’s purpose is. Clover Bloom tags along, wanting to discover what her life’s purpose is as well. But when they arrive, they discover that the unthinkable has happened: Cheese Sandwich has lost his laugh!
 
So the three, along with Sans Smirk, try all sorts of things to make Cheese laugh again, but all their efforts are in vain. Just as their about to give up, Pinkie Pie realizes why he can’t laugh: because he needs to SEE other poines laughing in order to make himself laugh.
 
Cheese Sandwich: Pinkie, you laugh at everything. I appreciate what you and Mikey are doing, but I think it’s a “cost lause”. [stutters] A lost cause.
 
Clover Bloom: [snickers]
 
Cheese Sandwich: What… was… that?!
 
Clover Bloom: Um, I’m sorry, Mr Sandwich. When you swapped the letters of those words, it was just a bit…
 
Cheese Sandwich: Funny?
 
Clover Bloom: Well, yes, yes it was.
 
[Cheese Sandwich]
 
So you’re saying it’s a mix-up
 
Of the sounds that I just made
 
That coaxed the snicker from your throat
 
In a delicate cascade?
 
If I did it one more time
 
If I reproduced that feat
 
Mixed up some letters here and there
 
You’d “lelly-baugh” tout suite?
 
[ponies laughing]
 
[Cheese Sandwich]
 
Then that’s all I need to do
 
That’s who I need to be
 
I thought I needed laughter
 
But it has to come from me
 
Squirting flowers and knobby knees
 
Rubber chickens my expertise
 
If you want laughter, then stick with Cheese
 
[ponies laughing]
 
Pinkie Pie: Yeah!
 
[Cheese Sandwich]
 
I suppose now I should amp things up
 
To get the thing I’m after
 
Move whole syll-AB-les around
 
And change em-PHA-sis to get laughter
 
Can’t stop now, I’m on a roll
 
I’ve almost got it back
 
Bright folks like you aren’t subject to
 
My play-on-words attack!
 
With something else, I’ll have to play
 
To get me where I’m going
 
Mikey: Whatcha gonna do?
 
[Cheese Sandwich]
 
[falsetto] Some Commedia dell’arte
 
To get the laughter flowing
 
And it’s what I need to do
 
It’s who I need to be
 
I thought I needed laughter
 
But it has to come from me
 
Follow right behind, if you please
 
Walk this way and I guarantee
 
If you want laughter, then stick with Cheese
 
Accordion solo!
 
Pinkie Pie: Shred it, Cheese!
 
[accordion playing]
 
Cheese Sandwich: Whoo! [laughing and whooping]
 
And it’s what I need to do
 
It’s who I need to be
 
I thought I needed laughter
 
But it has to come from me
 
Whoopee cushions and Dungarees
 
I know jokes like my A-B-C’s
 
If you want laughter, then stick with Cheese
 
[ponies laughing]
 
[Cheese Sandwich]
 
And now my biggest test
 
The hardest fish to fry
 
[Pinkie Pie]
 
Ooh-ooh-ooh-ooh
 
[Cheese Sandwich]
 
A mind so analytical
 
A sense of humor dry
 
[Clover Bloom]
 
So dry!
 
[Cheese Sandwich]
 
To make you laugh would prove to me
 
That this experiment’s done
 
[Pinkie Pie and Clover Bloom]
 
Ooh-ooh-ooh-ooh
 
[Cheese Sandwich]
 
Something ridiculous and not too smart
 
Something like a pun
 
Hey, Sans! How did the laughing bird’s eggs hatch? They cracked up!
 
[rimshot]
 
Sans Smirk: Sir… that is so… ridiculous! [laughs]
 
[Cheese Sandwich]
 
Then that’s all I need to do
 
That’s all I need to see
 
I thought I needed laughter
 
But it had to come from me
 
[All]
 
Squirting flowers and knobby knees
 
Rubber chickens and Dungarees
 
If you want laughter, then stick with Cheese!
 
[factory ponies laughing]
 
 
Their plan works and Cheese returns to his old self again.
 
Back at the castle, Pinkie Pie knows what her purpose is. Clover realizes that she was meant to be a dancer, as she had fun dancing to Cheese’s song, and get’s an idea for her and Melody to be a Singing-Dancing Duo. Mikey realizes that he wants to be a party planner like Pinkie and Cheese.
