You get ponies who put so many things on hot dogs: ketchup, jam, onions...but in Pinkie's case, she prefers the much more traditional mustard.

Not hot sauce, though. That is strictly an addition for cupcakes only. You are a heathen for even suggesting it.

I can see the things you're doin'
And you think that I'm naive
But I'm not into ketchup or
Getting jam on my sleeves
(That is if I have any sleeves
To get themselves smeared up in sauce)
I just don't see just what you're doin'
Why you'd put marmalade, stop and pause!

Don't think I'm not a hot dog gal
'Cause you better believe that we're all hot dog pals, it's true
You know it! (yeah)
You know it!
It's just that I simply prefer mustard!
(Mustard!)

I don't wanna put on mild stuff
And you better believe me
I want the sauce that'd turn normal tongues coarse and rough,
That mustard.
(Mustard!)

Yeah, you may suggest I use hot sauce,
The differences can't be profound,
But that's totally different of course,
To mustard!

You see one is colored red,
It looks like ketchup in your head,
And that's no good, cos in my food,
I want mustard instead.
And I don't care what you've found,
That's like saying square is round,
Or like saying up is down,
(Saying up is down)

It starts with a "M"!
(Starts with a "M"!)
It goes M-U-S-T-A-R-D!
That is mustard!
(Mustard!)

I would never ruin dogs in that way
And you better believe me,
That hot-sauce and mustard is like night and day,
(Totally different!)
It's mustard
(Mustard!)

Don't think I'd use hot-sauce or jam...
Yeah, no onions or anything...
(I don't wanna know)
This is how it's gonna be,
I'll always take hot dogs with one thing,
(I'll have it! I'll have it!)
With mustard!
