Put my face on someone else's in a video

[joeberman334]

All I want to do is take a video clip like, say, the scene from Friday where Debo knocks out Red and put my face on Debo's and my friends' faces on Red. It doesn't have to look good. I don't care about shadow, lighting, etc. As a matter of fact, the more crude it looks the funnier it will be. It would be awesome if the video editor was free, but I can pay a small price to insult my fantasy football league.

So there you go put my face on someone else's in a video.

Thanks!
