I'm sure you have stumbled across the Giraffe challenge on Facebook. Well, we're here to explain what it is, how to play, and what people are saying about it.

Here is the riddle:

It's 3am, the doorbell rings and you wake up. Unexpected visitors!! It's your parents and they are here for breakfast. You have strawberry jam, honey, wine, bread and cheese. What is the first thing you open?

The way it works is this. If you are able to get the answer right, then you do nothing. If you get it wrong then you change your profile picture to a giraffe. You might have noticed many of your friends on Facebook sporting giraffe profile images.

When you analyze the question you can make the assumption that you open the jam or honey. Maybe you open the wine if your family are alcoholics. Then think further into the question. Maybe you should open the door first. Then, think. It's the morning. You should probably open your eyes first. That is the answer, your eyes.

At this point there are no indications that this is any type of virus or malicious activity.
