You know you're behaving like an arsehole, don't you, BOx? That this intellectual dishonesty you practice is infuriating, insulting, and beneath even you? (You can't be quite as stupid as you're trying to come off as.)

And yet, you keep doing it, year after year. Ever seeen Forrest Gump? I think it is he who says, "Stupid is as stupid does".

Applied here, it becomes "Arsehole is as arsehole does".
