Can someone tell which Inuyasha manga chapter this happens in?!

Question: Its where Sango takes her Hirakotsu or however its spelled to get the poison off at a sages... while shes fighting the demon spirits of her weapon Inuyasha and shippo get drunk of the sake (the argument between Inuyasha and Kagome was so funny), anyone know what chapter this is? its in the 400's like 480 or something?
