We encourage our kids to tell the truth and have mastered the art of spotting a lie a mile away. But just because we preach honesty, that doesn't mean we always practice it. We asked our Facebook readers to share the biggest lies they've ever told their kids. While some answers were pretty standard (Santa Claus, the Easter bunny, and the tooth fairy), there were some that were so unique that they made us laugh out loud. Check out some of the responses, and make sure to share your go-to fib with us!
