Mareto is 2 months old and lives in Japan. His dad, Hirohito, recently tweeted this adorable (and slightly gross) video of little Mareto giving himself, er, a surprise. From his butt.
You can watch the video below.

The ridiculously cute vid has had thousands of retweets and Mareto is Internet-famous before he can walk or talk. Cutie!
