Newtons 3rd law

This video in my opinion was very useful as the man in the video shows real life situations in which he asks people questions about the gravitational pull between the earth and the moon, and despite these people knowing Newtons 3rd law (every action has an equal and opposite reaction) they still do not apply it to his questions. They think If an object has a greater mass it will has a larger gravitational pull, but i guess they just didn't fully comprehend Newtons law.
