Failure to solve a riddle being shared on Facebook is prompting thousands to change their profile pictures to an image of a giraffe.

The riddle – which has nothing to do with the African mammal , is said to be easy to solve, but is tripping many users up as it spreads around the social network.

The question asked in the challenge is: ‘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?’

(See the bottom of this post for the correct answer).

Facebook users who have failed the challenge must change their profile pictures on the site to a photo of a giraffe and re-post the riddle, asking friends to message them with the answer.

The challenge is spreading quickly. If they also incorrectly guess the solution, they must change their profile picture and post the riddle for their friends to guess, thus spreading the game further around Facebook.However, it is irritating but funny at the same time.
