I'm looking for funny sites, ones that can cheer me up every day or week with regularly-updated new material.

I've got:

http://dribbleglass.com/Jokes/bumperstickers.htm (updated intermittently)
http://www.homestarrunner.com/sbemail.html (mondays)
http://www.theonion.com/ (wednesdays)
The "links of the day" section at www.bluesnews.com (daily)

For cartoon strips, I've got:

http://www.userfriendly.org/static/
http://www.penny-arcade.com/view.php3
http://www.unitedmedia.com/comics/dilbert/archive

What else is good out there? By the way, I'm not looking for a single static page that's funny to read once. I'm looking for humor sites that are updated regularly.
