Mischief is one of the many Emotions that were first introduced in Animal Crossing (GCN) and then later appeared in Animal Crossing: Wild World and Animal Crossing: City Folk, which in these later installments could then be used by both the Player and CPUs through Dr. Shrunk(ACWW) and both Dr. Shrunk/Master Frillard(ACCF).
When the Mischief Emotion is activated, the user turns their body to the right side and hunch over slightly, concealing a sly expression on their face. While this is done, a quick shadow whips across their face and a glint is seen in either their right or left eye.

Here's Dr. Shrunk's act from his stand-up routine entitled "Mischief":
Thanks you! Thank you! And thanks to that special someone out there! I think you KNOW who you are! Dr. Shrunk is in the house!
Have I ever got a serious case of the up-to-no-goods today! Wanna know why? Yeah, I BET you would! Psych! Gotcha!
Heh! The doctor is OUT!
