HAHAHA! DUMB BABY DOESN'T KNOW WHAT TWINS ARE!
JK, this baby isn't dumb, he's a baby. Babies don't know the difference between toes and fingers, so I doubt they're able to grasp the complexities of having one of their parents be one half of two natural clones.
For some reason, the Internet is completely fascinated with the concept of tricking babies. It seems like the only socially acceptable form of bullying out there.
I guess the parents are kind of entitled to the tricks.
Like, they made this thing, they clothe it, they let it ruin every vacation they have and allow it to make them not get full nights of sleep for years. I guess they're kind of allowed to make the baby look dumb for YouTube views and Reddit upvotes.
