Haruhi: "Hey, mister green guy? Can I ask you something?"
Piccolo: "Sure, what is it?"
Haruhi: "You don't look human, and you don't look like your species reproduces like ours…"
Kyon: "Haruhi, don't go there. Please don't go-"
Haruhi: "Are you a Yoshi?"
(Goku laughs, Kyon sighs and facepalms)
Goku: "I asked him the same thing once and he said he was."
Haruhi: "Cool! Can I ride you?"
Piccolo: "Oh, for the love of Kami… whatever. Sure, hop on."
(Kyon sighs again and continues to facepalm)
