I annoyed not a few professors in seminary by bringing up edge cases in systematic theology, especially in thinking about bodies and souls. When cloning was denounced as theologically dangerous, I said I had two aunts who were clones — identical twins, in fact. Then I brought up Abby and Brittany Hensel. These charming girls are basically two heads on one body. Featured on Oprah and in Life magazine a decade ago, they’re now teenagers. I chuckle when I remember those theology classes, especially as it appears that the girls attend a Christian school. There’s lots of scope for juvenile humour here, especially as the twins share a single reproductive system.
