Lennard Davis grew up hearing from his parents that he should, at all costs, avoid being like his good-for-nothing Uncle Abie. Later, after his father died, that very same uncle told him that his father was not, in fact, his father. Instead, he said, Lenny was a product of artificial insemination, and he, Uncle Abie, was the sperm donor. At first, the evidence points to the possible truth of Abie's story, then more evidence seems to indicate he was lying. It takes Lenny more than 20 years to sort out whether it was true, and he finds out the answer—definitively—as tape is rolling. (31 minutes)
