The new poster for The Omen reminds us how to tell if our children are anti-christs. If you suspect your kid is a Satan, try to get him to walk into a sunset or towards headlights (maybe just drive at him) and pay careful attention to his shadow. If it's child shaped, you've got a kid; if it's cross-shaped, you have a Satan. Either that, or the kid might just have his arms out like a cross, so make sure his arms are down before trying to kill him for being a Satan. There's also another possibility, which is that the "child" you've been raising has just been a wooden cross.
