According to my mom, my first word was (looking up at the sky) 'Wow!'
This comic seems to be a follow up to 1115: Sky.
Here, Beret Guy claims ownership of the sky, which contains or "stores" the clouds. Last panel is a pun on cloud computing and specifically cloud storage, and looks like a follow up to 1032: Networking. The obvious joke is that, instead of “cloud” (Internet-based) storage, Beret Guy's business is literally storage of clouds.
The title text is a further statement, that his first words came while looking up at the sky. This relates to the first panel, where Beret Guy is shown hanging to the grass ceiling of an upside-down panel; the joke is that from an outside perspective not only would Beret Guy appear upside-down, but so would his written-out speech. As a child, Beret Guy would be looking up at his mom, and with a similar flipping of his speech his first word "MOM" would appear as "WOW".
There are some connections with both 908: The Cloud and the title text of 1444: Cloud.
