The video starts with the narrator saying he doesn't approve of his best friend Andrew marrying his little sister Lexi. To prove them wrong, he decides to throw them a dream wedding, honeymoon, and a series of challenges to test their compatibility.
The wedding planning ensues, and the narrator comes up with various ideas, including hiding the engagement ring in Lexi's favorite ice cream flavor and having Andrew dress up as a Disney prince. However, things don't go as planned, and they eventually settle for a more straightforward proposal.
The wedding ceremony takes place, and the narrator's friend Drew officiates. Just as the ceremony is about to conclude, an unexpected guest, President Obama, arrives to congratulate the newlyweds.
After the wedding, Andrew and Lexi are surprised with a honeymoon suite, but things take a turn when they're given a series of challenges to complete as a married couple. They're presented with a fake pregnancy belly, which simulates the experience of being pregnant, and are tasked with trying various weird pregnancy cravings.
Later, they're given a real baby to take care of, and they struggle to change its diaper and put it to sleep. Despite the chaos, they eventually manage to get the baby to sleep.
In the final challenge, Andrew and Lexi are hooked up to a lie detector and asked a series of questions. However, they fail to tell the truth, and as a result, they don't initially win a trip to Hawaii. But, the narrator agrees to let them go to Hawaii if the video gets 250,000 likes. In the end, Andrew and Lexi get divorced, but they can still go to Hawaii for their honeymoon if the video meets the required number of likes.
