In David Ives' play "Sure Thing," the two characters are Bill and Betty. These two meet in a restaurant. It seems that the story is based on maintaining political correctness.
Bill goes to the restaurant and asks to sit with Betty. Betty is apparently waiting for someone, but Bill is relentless, and she finally allows him to sit down with her; they begin to talk.
The comedy revolves around a bell that one of the two characters ring when the conversation takes an unwanted turn; the bell signals that the question asked or conversation being held begins anew with different results. With the bell ringing, it is almost as if the characters get to do an instant replay while editing, to bring about a different outcome.
The play's last line is "Sure Thing," which Bill says in agreement to what Betty has just stated.
(Video taped productions of this one-act play are available to view online.)
Where can I find the video for on line viewing please?
