Jokester Brother Brings Llama in a Tuxedo to His Sister’s Wedding to Fulfill Years-Old Sibling Promise

A 21-year-old college student is going viral for bringing a particularly spiffy guest to his sister’s wedding last week.

Mendl Weinstock showed up to his sister Riva’s wedding ceremony with a llama in tow. Not only that, the llama was wearing a tuxedo which he had custom-made just for the occasion.

Mendl says that he facilitated the amusing prank as a means of fulfilling a 5-year-old promise to his sister. The two siblings had been on a road trip from Ohio to Indiana in 2015 when—for one reason or another—Mendl joked that he was going to bring a llama to Riva’s wedding.

Since Riva was just 17 years old at the time with no concrete plans for marriage, she rolled her eyes and said Mendl’s llama would be invited to her wedding whenever it would be.

After Riva got engaged in October, Mendl knew he had to make good on his promise—so he reached out to a local farm and paid $400 to rent a sweet and well-behaved llama named Shocky for the duration of Riva’s wedding day.

“Ever since that day [in 2015] I have promised her I would bring a llama. I fulfilled that promise,” Mendl told USA Today. “She was shocked at first but more impressed that I kept my promise from 5 years ago.”

To Mendl’s delight, Shocky quickly became a beloved part of the wedding ceremony. In addition to the barnyard critter sitting politely throughout the wedding ceremony, he also posed for photos with the other wedding guests.

Mendl later posted a photo of his sister’s initial reaction to Shocky’s arrival to Reddit—and it has since been shared thousands of times across social media.

Although Riva was gracious about her brother’s gag, she says she does plan on getting him back during his graduation ceremony from the University of Akron in the fall. Mendl has agreed that this is only fair, but he has requested that his sister refrain from pulling any kind of prank or surprise while his name is being called for his diploma.
