Danger O'Riley

 is Pleasure O'Riley's younger sister. She is a model. Her real name is Dora O'Riley, but she goes by "D. D. O'Riley" for her professional name, which also includes her nickname, "Danger". The second "D" does not stand for anything.

Danger used to date a magician, but could never learn his tricks saying, "I didn't date him for very long."

Danger house-sits for Pleasure while she is away on her honeymoon. She has a series of household mishaps which Darrin offers to fix, much to the chagrin of Samantha who expected to spend the weekend alone with him.

After failing to woo Samantha, her former beau, George, begins to romance Danger and tells her that he is a warlock. She does not seem to understand or believe him, but she is not judgmental and accepts him for who he is.

Trivia
Some online sources list her last name as "O'Reilly", but this is incorrect. The mailbox and the credits list her as "O'Riley".
