I just tried pushing the screen of my PowerBook back... using the cursor...
Ranks right up there with when I tried to throw away a piece of paper by moving it to the trash, the virtual one mind you...
Or you spill coffee all over your desk and you go to push Cmd-Z (Ctrl-Z) to undo.
I had lint on my sweater and my first reaction was to use PhotoShop's clone tool to remove it...
