* This program displays a table of light bulb jokes,
generated from a MySQL database.
*
* This file gives a solution to the following
exercise:
* Create a MySQL database that contains one
table. The jokes table stores the light
* bulb jokes. For
each joke, the table stores the joke's subject (e.g., professors,
* computer scientists) and
the joke's punchline. Populate the table with sample data.
