Here's another explanation

The mother had heard someone talking about Simply Maya and the great Maya tutorials on the internet. She wasn't sure about what she had heard but she wanted to try anyway. She remembered this one sentence:

- Ok. Let's see... "First select the floor and then the foot. Then select Constrain -> Point..."
- Umm... Wait a sec! I don't have a computer and whatta heck is Maya anyway? I have a better solution.

So she went and got herself a hammer and some nails and point constrained the foot to the floor in the traditional way.

Just kidding...
