My dog’s favorite game was to have me grab his tail while he gnawed on my wrist until it hurt and I let go. My friends would think I was being mean to him until they saw how he would walk backwards trying to put his tail in my hand when he wanted to play.

He also liked licking my head while I was lying down. He was very thorough about it and when he was done with one side, he would wait for me to roll over so he could lick the other side. (A cat did that to me too once - maybe my hair is tasty?)
