"The Dentist of Seville" is a Sesame Street opera starring Placido Flamingo. In the play, he stars as the dentist, who asks his Anything Muppet patient to "abre la boca" (open your mouth).

The title is a reference to the famous opera, The Barber of Seville by Gioacchino Rossini, but the music is taken from the classic Italian song "Torna a Surriento".
