A riddle is going viral across the social media website, and if you get the answer wrong then you have to turn your profile picture into a giraffe.
The question is:
"It's 3 a.m., 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?"
Want to know the answer?
WARNING: Do not read past this point unless you want to see the answer!
ANSWER COMING UP:
According to the Chicago Tribune, the correct answer is "the door." However, some people are getting upset, saying the first think you'd open at 3 a.m. is your eyes because it's assumed most people are sleeping at the time. The Chicago Tribune later updated its story and said both answers are acceptable.
The Chicago Tribune also says reports of the giraffe riddle being a hacking hoax are not true.
