I urge all married men to give into their urges to seduce that co-ed who babysits their children or that young secretary at work. It's no big deal. If your wife catches you and feels betrayed, just say, "Honey, it couldn't have been evil. After all, I've done the same thing with you and you thought that was just fine."
After all, the same hip-thrusting action is going on in both activities. It's as absurd to call one "adultery" as it is to call the waterboarding of prisoners "torture." After all, we perform the same actions on our own troops in training, right? So it can't be evil.
