This isn't the first time I've seen a video of baby twins laughing at one another as if they were telling some kind of inside joke. It's definitely one of the cutest things I've ever seen, but I always end up wondering what's so funny. The noises that the baby brothers make seem like they're just sounds, but a part of me wants to know if there is some kind of communication taking place between the two. According to an article published by ABC News and written in response to a viral video of twin brothers talking to each other, some studies suggest that twins have the ability to communicate, even through unintelligible sounds, because of a shared understanding. We'll never know what the twin brothers in this video are laughing about, but I'm glad that they're in on the joke together. 

Everything about this video made us smile. We hope you enjoy watching this as much as we did. Don't forget to tell us what you think in the comments section below after watching!
