It's hard to write something about this video that isn't either a) self explanatory when you watch it, or b) doesn't give away some of the pure, unmitigated brilliance contained therein.

Well, not exactly rolling around on the floor, more swaying side to side on an office chair. But it definitely made us laugh... Big style.

Now it's over to you Mr Jobs... Or, at least, your lawyers...
