Problem: Joke and Punch line
A joke typically has two parts: a setup and a punch line. For example, this might be the setup for a joke: How many programmers does it take to change a lightbulb? And this is the punch line: None. That's a hardware problem.
Think of your favorite joke and identify its setup and punch line. Then, create an application that has a Label and two buttons on a form. One of the buttons should read "Setup" and the other button should read "Punch line." When the Setup button is clicked, display the joke's setup in the Label control. When the Punch line button is clicked, display the joke's punch line in the Label control.
