3. Strongbad Email:
http://www.homestarrunner.com/sbemail.html
Strongbad reads his email. You should probably check out the site first before you get into it, because it'll be more funny if you know the characters (
http://www.homestarrunner.com/characters2.html). There's plenty of other things on the site, but the real laughs are in the email.
Updated... weekly?
ADD THESE THINGS TO YOUR FAVORITES AND WATCH/READ THEM. I COMMAND IT.
