Sorry!  Commedia was at its most popular during the Renaissance (and mostly 1550-1750).

Sorry!  Homer Simpson is a modern Zanni.  He is lazy, and only thinks about food.

Sorry!  While the actors do interact with the audience, stock characters are used in Commedia dell'Arte.

Sorry!  The Lovers don't wear masks.  They wear heavy makeup instead.  All of the other characters wear masks.

Sorry!  Commedia was performed outside in the town square, making it accessible to people of all classes.  Proscenium (the most common stage today) and thrust wouldn't become popular until the eighteenth century, during the Restoration.

Sorry!  Unlike in Shakespeare's theatre company of around the same time (which only employed men), women were allowed to act in Commedia dell'Arte.  Of the average ten members in a Commedia troupe, about three of them would have been women.

Sorry!  Scenarios are outlined scenes that do NOT specify dialogue or blocking for the actors.  This allows them room for improvisation and interaction with the audience.  (Lazzi is the term for the business that makes a character recognizable.)

Sorry!  A slapstick is a prop made from thin wood that makes a loud noise when hit against something.  It does not hurt the actor who is being hit.  It is carried by Arlecchino--if, for some reason, Capitano got hold of a slapstick, he probably wouldn't have the courage to use it, and no one would hear the sound.
