This Video Of A Baby And Cat Watching A Rube Goldberg Machine Has The Perfect Ending

A baby's first years are full of monumental firsts. There's the first word, the first walk, and possibly the first time seeing a Rube Goldberg machine.

In this giggle-worthy video, a baby and cat are completely mesmerized watching a Rube Goldberg machine on TV. As the complicated chain reaction progresses, neither viewer moves a muscle or makes a sound. But the best part is the end of the video when they simultaneously look back at the camera with the same expression on their faces. The title -- which roughly translates to "Totally in sync! My son and Kitty" -- is very fitting.

What's even funnier is the fact that they both seem totally unfazed by the brilliant feat of engineering they just witnessed.

Baby is not impressed.
