We're all guilty of it: It's 4am, you have to be awake early the next day for work/school/responsibilities, and yet you've fallen so deep into a Wikipedia hole that you don't remember a time outside of it.
But we want you to share your time-wasting secrets with us. What's your favourite Wikipedia page to get lost in when you should probably be doing something else?
Maybe it was some creepy unsolved mystery that peaked your interest...
Or maybe you were sucked into reading about something a little more scientific.
Whatever it is, we want to know which Wikipedia article you just couldn't stop reading. Tell us all about it in the comments, and your submission could be featured in a future BuzzFeed Community article!
