Beauty Related Puns

So today in anthro we were discussing what methods are used in dating fossils and fossil sites. We started talking about using rock layers to date and he said "this reminds me of one of the colleagues I had. He was pretty young and when ever we had our get togethers he would bring this beautiful woman, different every time, that always turned out to be his cousin. Anyways this method is an example of relative dating."

There were a couple laughs and one audible groan.
