Here’s definitive proof that dogs are man’s best friend. This labrador retriever has been taught how to fetch a beer from the refrigerator and bring it back to his owner. However the labrador beertriever gets stuck in the fridge. Now this is a great idea if you’re a bachelor and all that is in your refrigerator is beer, but you have leftover sushi, a cherry pie and an entire roasted chicken in there then I imagine this delivery system probably doesn’t work so well.
