Super funny joke, is there?

Where does the milk come from? Child A: There are several mouths under the cow's stomach, from which it flows out. Are you sure that's a mouth? ) Continue to ask: How did coconut milk come from? Child B: Coconut milk is goat's milk. (digress, brother) continue to ask: what is goat milk? Child B: Goat milk is yogurt, right? Don't drink at home, order bright milk. (What terrible logic)
