Just another day in the life of Cheese the bearded dragon, and he has to make sure that the walls are doing okay - by running into them again and again and... yup, again. As the description of the video says: "Their depth of perception is pretty bad, but mine seems to have no perception of depth at all."
The exasperated and fond laughter of the owner, along with hilarious captioning and ingenious commentary, such as: "What are you doing?" and "Did you walk into the garbage can AGAIN?!" is just the icing on the cake. We've lost count of the number of times we've seen this endlessly amusing video, and you're about to as well.
