where could I find a picture of this..?

[☠Barbieâ˜]

i need a picture or a screen shot of a part of the "Nightmare Before Christmas" movie. I need a picture of where Jack is writing on the chalkboard trying to figure out christmas (ex. i think it says E=mc^2xChristmas tree or something like that) but the chalkboard has a bunch of stuff on it, and jack is writing on it.

i need this for a homework project...please help.
