Lucy:
Well, look here. A big yellow butterfly. It's unusual to see one of those at THIS time of year, unless of course, it flew up from Brazil. I'll bet that's it. They DO that sometimes, you know. They fly up from Brazil.

Linus:
That's no butterfly! That's a potato chip.

Lucy:
Well, I'll be. I wonder how a potato chip got all the way down here from Brazil!

Linus:
It was a short summer, Charlie Brown.

Charlie Brown:
And it looks like it's gonna be a looong winter.
