Brother of the bride plus one … llama. A New York woman named Riva Weinstock knows her brother would never break a promise, but this is one time she wishes he did. Five years ago, Mendl Weinstock told his sister that if she ever got married, he would bring a llama as his date. And last weekend, at her wedding, he made good on his promise. Mendl shocked his sister when he showed up with a llama, which he rented. Not only that, he even had a tuxedo specially made for the animal. He shared a photo of his special date on Reddit. Riva says she’s now thinking of ways to return the favor.
