What it says, fool, what it says. It's a girl on a cow. Why she is on the cow is a whole other question. Is the cow being led by the boy, or is following the boy naturally? Is the girl going to school or just for a ride around the neighborhood?
Original this cartoon had a speech bubble saying "Doctor can you bring my family a kid so I can play with him?" or something. Cute I guess, but not flexible in use. So I removed the speech-bubble (some of it morphed into the hedge) and provided it like this. The edges of the circle were originally missing too.
