Wikipedia Hole 

Going on to Wikipedia to look something up, then unexpectedly being sucked into a seemingly endless series of link clicking to end up in a completely different part of wikipedia than you ever meant to go to.

I just went to Wikipedia a high school in Bangladesh, and I ended up on an article about Cottage Cheese.

Dang, looks like you fell into a Wikipedia Hole.

Wikipedia Rabbit Hole 

It's not just a hole. It's a rabbit hole, akin to the one Alice fell down to Wonderland.

I enjoy falling down Wikipedia rabbit holes because I never know where I may end up.

"I googled 'Roald Amundsen' and knew I'd gone down a 'Wikipedia rabbit hole' when I ended up reading the lyrics to the 'Star Spangled Banner'."
