Here's how it goes:
"It's 3:00 am, the doorbell rings and you wake up. Unexpected visitors. It's your parents and they are there for breakfast. You have strawberry jam, honey, wine, bread and cheese. What is the first thing you open?"
According to the riddle's rules, set forth by vlogger Andrew Strugnell via YouTube and Facebook last week, those who fail to answer correctly must replace their Facebook profile picture with a photo of a giraffe, accompanied by the following explanation: "I've changed my profile to a giraffe. I tried to answer a riddle and got it wrong. Try the great giraffe challenge!"
To help you stand out from the rest of the herd, we'd like to suggest the following 8 giraffe photo options.
