A creepy guy, reminiscent of Woody Allen, who takes much too much interest in hugging, playing with, and taking nude pictures of, small children. Especially a family member who has these tendencies. The ultimate example of this is marrying your almost-adopted foster child who you photographed nude for several years.
Oh look, if it isn't Uncle Woody. Hide the kids.
