Who says twins have to be the same exact person? These adorable babies couldn't be further apart while watching and listening to the nursery rhyme "Old MacDonald Had a Farm." While the sister on the left is joyfully clapping and singing along, the one on the right fixes her with a death state until finally dancing along at the end. Mom Regina Durante submitted the video to Scary Mommy Time Out, and we're so glad! Absolutely hilarious.
