PANG gets angry very easily recently. He blames everybody for not taking good care of their teeth. YEE finds out that PANG has got a decayed tooth but he is afraid of visiting the dentist. Everybody try hard to push him to the dentist. YEE accompanies PANG to the dental clinic but he leaves early to settle some ad-hoc business matters. When YEE returns, he is shocked to find that the dentist has passed out and PANG is nowhere to be seen!
