Need to make unclosable video

[theredx219]

Hey guys, my brother is going to be borrowing my computer next week and for a prank, I'd like to put a video in the startup so it will automatically play. The problem is, he'll probably close it before it starts or before its played for more than a few seconds. I need him to watch the whole thing. Could somebody help me out with making a video window that will not close?

You can't do it unless you wrote your own video player. . .
