The Lion, The Switch, and the Cuckoo: Adultery in a test tube

With special guest:
- Jonathan Grindon
A cuckoo has achieved its notoriety due to its practice of laying its eggs in the nests of other species, tricking parent birds into raising unrelated offspring when they hatch. Our guest today is Jonathan Grindon who due to the deception of his then wife, Annette, experienced firsthand that this behaviour is not confined to the animal kingdom.
This is not the usual way that husbands may be cuckolded. Jonathan was a sperm donor, the biological mother is an unknown Spanish woman and the embryo was placed in the womb of Annette. But wait, it was revealed some six years later that in fact the sperm had been substituted, the biological father of the child was not Jonathan at all but a previous boyfriend of Annette’s who happened to be in the vicinity of the IVF clinic when they were implanting the seed.
