This tutorial is not to be followed except by absolute newbies at editing. This is super quick and easy and can be used in most basic editing programs.
You CAN use Windows Movie Maker to clone. Thanks crosbone for the heads up.

Ayumilove has a tutorial showing how to do it
If you actually do know how to edit, then you probably already know how to clone and will know that this technique is bad, inaccurate and not efficient.
For those of you who are more advanced than beginners but don't know what to do, search up cloning and masks. Best tool for cloning IMO is with after effects.
Here's a Written Tutorial.
Basically, You use a tripod to film yourself at different locations making sure that the camera never moves at all. Then you take that footage and make cuts so that all you have is the person at the different locations (cutting out the parts where the person is walking to the location). Now put those cuts on top of each other so there is different layers. Use the crop tool and crop the top layer so that the layer under it shows the person at the other position. Work your way down the layer, showing a new clone every layer. And that's it.
