I read these comics/sites/blogs every day. You probably should too. I'll categorize them so you can select accordingly.

Questionable Content
Dinosaur Comics

For the nerd:
Knitting Things
More knitting things...
Even more knitting things....

In the event of emergency:
Cute Overload

In the event of a "not knowing what lindsay lohan was wearing when she got out of rehab (the 1st time)" emergency:

When you spent two hours reading Perez Hilton and feel like a jackass:
Teacher stuff
More teacher stuff

What do you read every day?
I showed your cat video to a coworker and said, "This is how my sister feels today." She said, "That's so funny because I have a cat image that expresses how I feel." Then I said, "Oh god, so do I."

We shared the images/videos. We laughed. We commiserated. Then we promptly went back to our desks keenly aware that we had just shared THREE different anecdotes involving cats. We don't even LIKE cats. And how many cat stories do you have to tell before you're a crazy cat lady? Oh, the horror.

But let's not think about that. I have included our videos/pictures for your viewing pleasure. And I feel compelled to say that we will be on our way to happy hour, promptly.
This is my coworker's life metaphor.

This is mine.
