Why do we have butts? ft. John Cena

393 ratings | 36566 views
In which John Cena asked the age-old question, “Why do we have butts?” and I went on an epic mission to find out. My journey took me from the simplest of creatures in the ancient seas to a lab at George Washington University—and finally to the earliest stages of human development.

Stumbled across this on YT crawl. The number of views is unacceptable! I mean, really, it's got it all! Music (with lyrics that would make John Lennon jealous), adventure and intrigue (what IS the evil butt scientist's master plan?), and even a love story that makes the Notebook seem like Schindler's List (my GOD the sexual tension between John Cena and Gladys! Will they? Won't they? Ross and Rachel who?). Clearly Oscar bait. Sincere part: Science FTW. This was fantastic and clever. Support smart art. =]

Extra points for the flying toasters.
A lot of YouTubers have been doing farting videos. And butts are the worst things on human beings because they make people die

I like butts. Great video! Never seen a video of yours but I am perusing the rest of what you have meow. I found out about deuterostomes in 4th grade bio and was fascinated at the progression of evolution and the overall system of how evolution happens. I always theorized it was fertility based once I learned about child birth as a lad just because it makes sense. Just like why women have breasts or why we sometimes cheat in otherwise happy relationships. Instinctual sexual drive yeet. Plus that definition makes me feel better knowing I wasn't cheated on a bunch but it was just that 😂😂😂😫
