Homeschool Joke

A woman talked at our homeschool meeting last night about getting your kids into college. She used this joke to illustrate, that the academic part isn't the problem:

Q: How does a home schooler change a light bulb?
A: First, mom checks three books on electricity out of the library
Then the kids make models of light bulbs.
They 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.

I heard that and I didn't get it. I'm wanting to know who is this homeschool mom and can she give me more ideas?!
