Here is what is known about Sammy Baby:

He is a he. He is a geek, and thus holds fervently to the hope that geeks make good boyfriends.
He is embarssed to admit that he likes Buffy the Vampire Slayer. His wife plays a character on a M.OO who is based on Willow. He digs Willow, but probably not as much as his wife.

Otherwise, he remains shrouded in mystery...
