The Melancholy of Haruhi-chan Suzumiya - Season 1 Episode 2 Huh? Only Nagato?
Overview: Kyon first arrives at the clubroom, only to be deafened by Haruhi who is throwing a tantrum because she is bored, which drives away a client. Shortly thereafter, Kyon finds Yuki playing an eroge on her laptop with the volume turned up. Kyon provides her with a set of rabbit-shaped headphones to keep the 'questionable sounds' from being heard in the room. Shortly afterwards, Kyon is accosted by Ryōko Asakura who attempts to kill him, but is stopped by Yuki. Before she fully dies, she informs Kyon that there are others who will attempt to kill him besides her, only to be interrupted by an exasperated Kyon, who nonchalantly states "the butler did it".
