Jeffrey Harrison, 50, lives in his RV near Venice and makes by his admission a "meager living." In the '80s he earned $400 a month as a much-requested sperm donor for California Cryobank. This year for Valentine's Day, he is meeting some of the teenage girls he helped spawn. He hooked up here yesterday with Ryann M (pictured) and has been in contact with six other offspring in recent days. They all had gone looking for information on their biological father, who was known to them only as Donor 150. "It’s a short life,” he tells the New York Times' Amy Harmon, who originally wrote about the search for Donor 150 two years ago. "And these children need to have some kind of resolution. I thought I could send a little valentine, kind of, to everyone, just saying hello." I'm told that everyone from "Today" to "Nightline" to KCAL has called looking to follow up. Prediction: Harrison will soon be everywhere.
