Okay, so it’s an episode where Pinkie is following behind somepony and she’s talking really, really fast. Not like she normally does, it’s almost completely unintelligible. All I could make out was “…and chip a tooth?” or something like that. It’s definitely not the episode where AB chips her tooth though, and I believe this might have been S3.
 
Help?

I can’t really recall any episode from Season 3 where Pinkie Pie was following Twilight Sparkle while talking fast.  
The closest i remember was the interaction they had in the beginning of the third episode Too many Pinkie Pies.

Where were they in the scene?
 
The only time I can think of Pinkie talking really fast and following somepony was in the first episode when Pinkie was following Twilight in her house and talking really fast.
