Here’s a nature fact they won’t tell you on Planet Earth: deer are the absolute stupidest animals. Name another creature that’s dumb enough to jump through the windshield of a bus

So when a deer decides to go to the gym (entering by crashing through a glass window, naturally) of course he forgets his headphones at home like an idiot and has to go back home.

A guy inside the gym also captured footage of the deer trying to jump through a mirror. 

The good news is that, even though the deer only got in about two minutes of cardio, he escaped unharmed.
