"on the lighter side" could be stories that are probably funny or ironic

When a chicken stumbles while crossing the street, that's a road trip.

Music student : "What are those papers the orchestra leader is looking at?"
Music teacher : "That's the score."

Music student : "Oh, Who won?"

What has four wheels and flies?
A Garbage truck.

닭이 도로를 가로질러 건느다가 넘어지게 되면? 그건 Road Trip 도로여행?
그런데 여기서 trip 은 to stumble, esp. by catching the foot. 발에 뭐가 걸려 넘어지다.
즉 도로상에서 넘어지다 뜻?

Score: a piece of written music showing the parts for all the instruments and voices:

가베지트럭에는 파리들이 많이 달라붙어 있답니다.
바퀴가 네개 달려있는데 날아다니는 그 무엇이 아니구!
