cosmo sucks.

Is this even a question Cosmo obviously.

So which is which

@Background Pony #D301  
Too true…

I always thought Patrick was the dumb one, but I guess Cosmo just doesn’t even try.

@FeatherTrap  
This

Two of them are stupid on their own way.  
One is silly and clumsy.  
The other one… is just stupid.

@SinnerWhoKeepsTrying1978  
I interpret her as an eccentric genius. Somewhat ditzy in day-to-day things, as geniuses often are..

OP

this is blasphemy

derpy is smarter cosmo is a moron how dare you compare her to that idiot

I don’t know anything, really, about Cosmo. But, I wouldn’t be surprised to find out that Derpy’s smarter than we even suspect she is.

but JonathanBML strike again.

@Astrohippus23  
Agreed

Wanda. She married him.

@Astrohippus23  
Agreed, this is cannon.

 
OP, you blue-winged teal: I know zero about Cosmo, but I know that Derpy is NOT stupid!

Cosmo.  
Derpy wasn’t around enough to be flanderised into the “HAHA HE’S SO STUPID REALITY WARPS AROUND HIM TO MAKE THINGS DUMBER, HAR HAR HAR!!” cliche that happens with every character who’s supposed to generate some comic relief by being “Not Bright” by the writer if the show goes on long enough.
 
For some reason writers don’t think it’s enough to have a character who’s simply absent-minded or lacks foresight, not after the first few seasons anyway. No, they always end up being “THE DUMBEST FUCKIN’ MORON TO EVER EXIST, LOL!!!”. Thank God Derpy didn’t get enough screentime for that to properly happen to her.

You

Cosmo. Derpy’s not stupid.

Derpy Tries to be good. Cosmos doesn’t even try to be normal.

Not even a contest, Cosmo.

Cosmo’s a legitimate self-admitted idiot, but Derpy’s just trying her best - c’mon OP
