Sorry, buddy. Gotta send you back to the Spirit Realm. Skadoosh! [flexes his pinkie, nothing happens] Okay...That didn't work; let me try one more time. Skadoosh! Skadoosh, skadoosh...! What the...?

Hold on, wait! It is working! No! No, no! No! No! Oh, no! No, no, no, no, no, no! No! [retches, then laughs] No, it's not. Did Oogway teach you that little trick? Too bad. It only works on mortals, and I...am a spirit warrior.
