Redditor Josh5591 was at work doing work stuff when he looked down at his desk and realized that something trippy was going on: his ruler was defying logic, thanks to to the help of some well-placed paper.

Keep staring at the ruler. It's straight—honest to God, that ruler is straight. 

It's a tough fact to accept.
