How does a homeschooler change a lightbulb?

This was written by a friend of mine and I thought it was hilarious:

First, mom checks three books on electricity out of the library, 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.
