Dimples...I mean Nipples

Lukey used have have fairly prominent dimples. My mom loved this because she, too, has dimples. I can still catch a glimpse of one when he smiles, but they do seem to be disappearing. The other night, Mom asked him, "where did your dimples go, Luke?" He gave her a puzzled look and then pulled up his shirt and said, "my nipples right here!" I have no idea how he knows those things are called nipples, but it's pretty damn funny.
