Happy New Year, Charlie Brown1986

Charlie Brown:
I've written an invitation to the Little Red-Haired Girl. I was afraid to call her. It's too late to mail it, so I thought I'd take it to her house, but I'm worried.

Linus van Pelt:
Why? All you have to do is slip the letter into the mail slot in the front door of the house.

Charlie Brown:
But what if my hand gets caught in the mail slot?

Linus van Pelt:
That's ridiculous, Charlie Brown!

Charlie Brown:
Well then, what if my hand gets caught in the mail slot, and while I'm hanging there, someone opens the door?

Linus van Pelt:
Charlie Brown, you worry about the most impossible things.
