My wife was a great cook when we got married, but she had never been shown how to fry bone-in chicken. She gave it a whirl the first week home from the honeymoon. It was the most beautifully golden, crisp skinned chicken you've ever laid eyes on... and completely raw in the middle.
I didn't say a word, just ate around the edges and prayed for protection. When she realized it she cried and cried... and went to my grandma for lessons. Score that as a WIN!
