Mark Zuckerberg's dating advice to young women!

Responding to a grandmother's comment saying she keeps granddaughters to date a nerd, Mark Zuckerberg said they should instead *be* the nerd instead.

Mark Zuckerberg had an excellent piece of advice for a grandmother who joked about persuading her granddaughter to date a "nerd" at school. In case you missed it, the Facebook CEO announced on Sunday that he's building a robot butler.

In the comments below his Facebook post, messages and questions poured in from Facebook users.

One user -- a grandmother -- posted the comment: "I keep telling my grand daughters to date the nerd in school, he may turn out to be a Mark Zuckerberg!"

But Zuckerberg recommended that they do one better: "Encourage them to *be* the nerd in their school so they can be the next successful inventor!"
