Another Light Bulb Joke

Here's some humor to "lighten" things up for you:

Q: How does a home schooler change a light bulb?

A: First, mom checks out three books at the library on electricity, then the
kids make models of light bulbs, read a biography of Thomas Edison and do a
skit based on his life. Next, everyone studies the history of lighting
methods, wrapping up with dipping their own candles. Next, everyone takes a
trip to the store where they compare types of light bulbs as well as prices
and figure out how much change they'll get if they buy two bulbs for $1.99
and pay with a five-dollar bill. On the way home, a discussion develops over
the history of money and also Abraham Lincoln, as his picture is on the
five-dollar bill. Finally, after building a homemade ladder out of branches
dragged from the woods, the light bulb is installed. And there is light.
