What are some of the most useless security questions you've been prompted to give the answers to when accessing an online account?

For example, my ATT account asked “Who was your childhood hero?”
Well, I didn’t need to access the account until a year and a half later, and damned if I could remember what I answered!

Other questions that could change over the course of time, or might be impossible to remember:

What is your favorite food?
Who’s your favorite kid?
What is your husband’s mother’s mother’s father’s mother’s maiden name?

Do you have any examples of the worst security questions ever?
