Why it worked
The video likely worked due to the relatable and humorous situation of a child interacting with an animal, combined with the recognizable personality of Dr. Pol, which appeals to his existing audience.
Summary
The video features two individuals, likely Dr. Pol and his wife, reacting to a clip of a child feeding a calf. The child appears to be struggling to feed the calf, and the couple laughs at the situation. The on-screen text "AND SHARE ALIKE" appears at the end of the clip.
