What the fuck do horses have to do with gift giving and what does being unappreciative have to do with looking in mouths?
When buying a horse you can check it's teeth to age it. As horses age their teeth begin to project further forward each year and so their age can be estimated by checking how prominent the teeth are. To do so on a horse given to you for free is an insult to the giver.
