The students walk around and ask their classmates the questions starting with "Do you have a/an"

Prompt the students to not reply if the question isn't formed correctly.

Have them reply with "Yes, I do." "No, I don't."

You can play it as a game with the student who first filled in all fields with a name wins. Have him or her correctly read "X, Y and Z have an unusual pet."

You can also use it as a prompt for further dialogue in higher levels. Have students describe their unusual pet or problem or talent. 

Have fun!
