Do not gloat when your enemy falls; when he stumbles, do not let your heart rejoice, or the LORD will see and disapprove and turn his wrath away from him. Proverbs 24:17-18
Michael Moore may be an exception to this, however. ;)
Serious question: If I gloat here at home, in privacy, is that still wrong? Because I know I give in to my appetites too much, but I really, really love this thread.
