Conversations with Knuckles

Knuckles: Sun's up!
Me: And Knuckles is up too! What will you do with the sun?
Knuckles: (puzzled look)
Me: Will you play with the sun? It looks like a ball!
Knuckles: It's not ball!
Me: It's not?
Knuckles: No, it's CIRCLE!
Me: It's a circle?
Knuckles: Yeah, it go up and down!

Well, there you have it. The sun is a circle that goes up and down. :)
