 Returning to the hotel , Moon started a food fight and soon cake began flying through the air . The drummer knocked out part of his front tooth ; at the hospital , doctors could not give him an anaesthetic ( due to his inebriation ) before removing the remainder of the tooth . Back at the hotel a mêlée erupted ; fire extinguishers were set off , guests ( and objects ) thrown into the swimming pool and a piano reportedly destroyed . The chaos ended only when police arrived with guns drawn .
