Just saw this here (link below) and figured I’d do an edit where Applejack looked more dazed/silly only because I didn’t like her in the episode. She did a bad job of making Rainbow Dash realize what she did was wrong. “Joke shortcut” / “no effort” / “lazy” are all criticisms that imply the problem is her jokes/pranks suck, not that pranking on unwilling friends is a dick move.

Something about Rainbow Dash getting the better of a cocky Applejack who ended up face first in muddy pig pen utterly defeated was satisfying and hilarious.
