Osuwari

The sit gag is a running gag in the series that has Kagome Higurashi saying a varying phrase that ends in Inuyasha falling flat on his face. There are many times in which she abuses this power such as when Inuyasha is annoying her or she doesn't feel like talking to him. Kagome got this power after Kaede placed a necklace on Inuyasha that gave control over him to Kagome. Some have tried to tell Inuyasha to sit but have failed to get the same results as Kagome is the only one who can control him as such.

Examples:
Kagome and the gang are waiting for Inuyasha to get done speaking with Kikyo and when he gets back Kagome becomes frustrated by his unwillingness to talk and repeatedly says "Sit, boy!" until he is implanted in the ground.

Inuyasha is picking on Shippo and Kagome yells "Inuyasha, sit!" and he falls flat on his face.

Kagome is upset with Inuyasha and has decided to not talk to him. Inuyasha determined to get a response from her keeps egging her on and in retaliation of this annoyance yells for him to sit which makes him once again fall on his face.

Inuyasha and Kagome are going back and forth over whether or not Kagome is crying and she tells him to just shut up and sit.

Inuyasha is unknowingly being rude or saying something that might offend someone else and Kagome tells him to sit to get him to be quiet.

Trivia

 * In Inuyasha the Movie 2: The Castle Beyond the Looking Glass, Kagome used the "Sit Boy!" command in such a way that it saved his life (it pulled him to the ground before he was struck by a move that he couldn't have dodged otherwise). It is the first time that the spell that usually puts Inuyasha in pain saved his life.
 * There have been instances in which Kagome was able to activate the "sit!" command using the word "stupid".
