Alternate Story:  
Twilight Sparkle: [sigh] Sorry Mrs Cake. Looks like the writing on the cake looks more like HAPVW MNULH MILNUM NIM.  
Mrs Cake: That’s okay Twilight. Be careful at times.  
Twilight Sparkle: May I have another cake to carry to Pinkie’s farewell party that says “Happy Birthday Pinkie Pie”?  
Mrs Cake: Sure thing.
 
Twilight Sparkle: Rarity, pass it to Fluttershy!
 
 
Rarity: Fluttershy, pass it to the party!
 
 
Fluttershy: [gasp] Sorry to interrupt–I have something important to give to!  
Pinkie Pie: Okay.
 
 
Twilight Sparkle: Here!  
Pinkie Pie: THANK YOUUUU!
 
This is the alternate story if Twilight, Fluttershy and Rarity were careful enough to keep the writing not ruined.

Derpy: Oh yeah, Well then Muffins are the Truth!!!

Pinky: The cake is a Lie!!!!

This.
 
The only longest streak of readable writing on the show is the “Welcome Princess Celest” banner from Swarm, and not how that’s simple lettering on a white BG, allowing for easy swap in any other language (if they chose to do so).

@Mad Black  
so it doesn’t have to be translated for international audiences. it’s the same reason twilight’s checklists use symbols instead of writing

Actually it’s “Hapvw Mnulh Milnum Nim”, Pinkie…

But I like metaoverthinking almost as much as I like abusing prefixes!

LOL…XD is not a smudge, that’s how they write!…haven’t you seen the signs(most of them anyway) or the board on Cherrilee’s classroom? XD

Hush, don’t overthink the overthinking.

why would only the writing be smudged?
