Well, you don't see that every day! This man saw a deer walking through his yard and decided to capture it on film. Apparently, the deer was pretty interested in the camera. As you see, he just walks right up and give it a lick. YouTuber A Bad Idol describes it for us:

A deer walks up to me and licks the lens of my ContourROAM2 on my porch. (Upstate NY by the Hudson River)

I was not and would never feed wildlife. It teaches them terrible behaviors that can be dangerous. It seems that neighbors have been feeding him for a while which led to his odd behavior. I was very lucky to be able to catch this moment because he thought the camera in my hand was a carrot or something similar.
