I'm all about "Stare Master", it's just plain hilarious for me.
The way Sweetie Belle present the CMC capes to everyone and Rarity's reaction to it, the whole crusading game as "creature catchers" and the table fixing, Fluttershy's stare to the chickens, the CMC's argument about how to call the chicken and at the end the way Fluttershy's lower voice did a lot more than Rarity's yelling to the fillies. A great episode that got me laughing like a maniac.
