CHALLENGES

1. Improve the Joke Machine by adding additional buttons along with additional jokes.

2. Currently, the Joke Machine game displays the text string of Form1 in the Windows title bar. Replace this text string with the phrase "visual Basic Joke Machine". (Hint: Click on the form and modify the form's Text property.)

3. As it is currently written, the TextBox field on the Joke Machine window allows the user to enter text into it, when it should really just display the text of jokes. Prevent this behavior from occurring. (Hint: Click on the TextBox1 control and set the Readonly property to True.)
