Not very deep

Charlie Brown: Next year I'm going to be a changed person.

Snoopy: Yesterday I was a dog. Today I'm a dog. Tomorrow I'll probably still be a dog. Sigh! There's so little hope for advancement.

Somedays you feel like Charlie Brown, some days you feel like Snoopy!

Here's a happy thought to end it all

Snoopy: My life has no purpose. My life has no direction, no aim, no meaning. And yet I'm happy. I can't figure it out! What am I doing right?
