One teen now has conclusive proof not to mess with squirrels, especially ones that happen to be sensitive to a camera flash.

Seventeen-year-old Brian Genest was in Florida with his family when he spotted a friendly-looking squirrel along the walkway. The animal even complied…until the flash from the camera caused a sudden change of heart.

 “Next thing I knew, the squirrel was on my shoulder, then under my shirt, and then hanging off my back!” Genest told BuzzFeed.

Genest’s mother snapped an “after” shot as the squirrel clung to his shirt as the teen flailed in attempts to get the animal off.  The squirrel eventually took off back into the woods. Click here to read more.  

Genest and his family are still chuckling about the experience and are stunned at how much attention the chance encounter has received.
