The moment at birth, examining a family photo, or just at random when you realize your offspring look nothing like the silicone bag bearing, botox injected, liposucked, rhinoplasted, forehead lifted, and tummy tucked person you call your wife. When you realize you've been duped and that your wife hasn't fully revealed the quantity of plastic surgery she's had done. This epiphany may also be triggered by a family photo causing you to suddenly understand why your wife looks as if she just stepped out of Vogue compared to the more homely qualities of your children.
