How many Father's Days are going to be spoiled when the adult Flannery O'Flanagan calls up the homes of his senior citizen parents, Conan & Margaret O'Flanagan, and says 'hey, my DNA test shows I'm 1/2 Mexican! How the heck did that happen, Mom?" ;-)

40 years ago, in a college genetics class, the instructor mentioned that - even given the relativly primitive non-DNA testing available at the time - a study he participated in a hospital in Madison, WI in the early 1960s indicated that 4-5% of births were children that could not have resulted from impregnation by the father of record. (The blood was collected as part of a sturdy of a different question. And no, they didn't tell either parent.)
