WATCH: Friendliest 1,500-Pound Bear You've Ever Seen?

A couple named Jim and Susan operate a shelter that takes in orphaned animals. One of their favorites is a 1,500-pound Kodiak bear named Jimbo that came to them as a cub. It had a serious leg injury and wouldn't have survived in the wild. Jimbo's now 23 years old and loves to play, which is pretty obvious when you see the video of him rolling around with his best buddy, Jim.
