This is pretty small to read, so you can click on it and it should get bigger or read below:

The upper right hand corner panel reads:

Charlie Brown: Isn't there anyone who understands what Christmas is all about?

Linus: Sure, I can tell you what Christmas is all about.

Middle panel:

Linus: December 25th is associated with the birth of many pagan gods including Mithra, Horus, Hercules, Zeus, and Sol Invictus. The Roman festival Saturnalia would also end around this time. Christianity imported many of these pagan myths and traditions into it's own customs around 400 AD.

Linus: Today Christians express outrage that Christmas is losing it's Christian roots. This is ironic since it was Christianity that hijacked the holiday in the first place to make it easier to convert new followers.

Linus: Nevertheless, it is a wonderful opportunity to share our love with friends and family, and commit acts of goodwill for those that are less fortunate. It is a time for children to revel in their innocence and wonder about the world, and adults to find their inner child.

Bottom panel:

Linus: That's what Christmas is all about, Charlie Brown.

I couldn't have said it better myself. By the way, has anyone seen my inner child???
