Gintoki’s mouth is swollen like crazy, forcing him to go to the dentist for treatment. Unable to cope with the stress and pressure of waiting, a crazed Gintoki screams for someone to just kill him and be done with it. After getting scolded by the staff, Gintoki waits for his turn when another man with a swollen mouth comes in, making things even more complicated!
Like Niwa-kun's place where you go
in the door and it smells like a toilet!
Es como la casa de Niwa-kun, 
que entras y huele como un inodoro.
Esse cheiro de banheiro parece o cheiro
 de quando se entra na casa do Niwa!
