How many Harvard students does it take to change a light bulb? (This is my favorite one)-One. He holds the light bulb in his hand and the world will revolve around him.

This is a joke about Harvard. A man stands still on the bench, and then the whole world revolves around him. Using the principle of relative motion, the light bulb naturally spins up. Harvard motto: be friends with truth. It seems that Harvard people are the representatives of truth, which subtly satirizes the arrogance of Harvard students. However, who can deny that the students lucky enough to enter Harvard do have proud capital: there are the lowest admission rate, the fiercest competition for admission, the world's top academic figures gathered here, and countless world firsts she has nurtured. The first thing that Harvard University can give students is this feeling of "king's respect".
