There are several different ways to open a letter, you can use your bare hands to rip it apart or if you’re more sophisticated than that, you might even use a paper knife. But have you ever thought of using a live rabbit to do the job for you ?
In this video shared by Dr. Yosh, you can see a cute little bunny happily doing the aforementioned job for his human in a neat and precise manner. I bet you too will want a bunny opener after watching this!
