The phrase "don't look a gift horse in the mouth" may seem like a rather strange saying, but it makes more sense when you know the origin. It refers to the practice of evaluating a horse's age and health by looking at its teeth — in other words, questioning the value of a gift by inspecting it for small flaws. When Chuck Stubbings, of Huntington Beach, California, received this 1966 Mustang as a gift, it had its fair share of flaws. However, he happily overlooked them and embraced the opportunity for a fun restoration project.
