how do i make those stick figure movies?

google pivot stickman

I believe most of the developers that create those movies use a program called Adobe (Macromedia) Flash. Unless you want to create thousands of GIF's and use a GIF animator of some sorts. But you can buy Macromedia Flash for relatively cheap, especially if you are student, and there are an immense amount of tutorials available online for free, and also there is a diverse community of people that are willing to help as well.

crap i knew of a program, spiz morph or something but you could take pictures of individual pictures and, load into Windows Movie Maker

Try Macromedia Flash.

It's kind of expensive.

Very carefully
