Adventures of Donkey Boy and Friends

Donkey Boy: "Hey Sticky, how come you only see stars at night?"

Sticky: "Well, Donk, the stars always there. So I guess that people just don't notice them during the daytime, because they're all worried about the day's problems and stuff. But at night, when they're done worrying, that's when they notice."

Donkey Boy: "But what about those people that never stop worrying - even at night, Stick?"

Sticky: "...Guess they never see stars, Donk."
