From guest blogger Vern of http://my-stuff-and-stuff.blogspot.com/:
This is one of the strangest things yet. Now, the California Cryobank (CCB) allows you to choose a sperm donor chosen by the best of their subjective abilities to be celebrity look-a-likes. They have hundreds of actors, musicians and athletes to choose from with links to pictures of celebrities in case you’re not sure what they look like. (So if you just want to pick some random celebrity for your kid to look like?!) Some famous names include Van Halen, Yao Ming, Adam Sandler, BJ Penn, Balthazar Getty, Antonio Banderas, Cedric the Entertainer and Christian Bale.
I did a search for Prince William (handsome young lad) and this is how his profile reads:
Ambitious and Adventurous
“At 6’3”, 203 lbs, Donor 11194 towers over the competition. He’s also a charmer with blue eyes, blond hair, and a friendly smile on a handsome face. He plans to express his creativity through acting and directing professionally, and hopes to become a catalyst for positive change in the world. The son of an English/Hungarian mother and a German/Dutch father, he’s a gentleman in the Old World sense, placing a high value on honesty and honor.”
His vial costs $490. Oh, and this donor also resembles Rick Shroder – yikes.
