For some of the Web's more respected names, it's a really special day. They get to treat their readers and fans with the contempt they hide most of the year. Below, five pranks today that show just how much the Internet hates you. And I do mean you.

• 1. InfoWorld claims Microsoft bought Yahoo. The respected tech trade's article is so straight-faced and credible that other journos weigh in seriously on the deal.
• 2. CollegeHumor.com serves up a single parody MySpace page. Way to take a vacation today, lusers.
• 3. CNET publishes the Urlrurl hoax we refused to run, plus a hoax about Intellipedia wars. What else should we not believe on CNET today?
• 4. Gawker Media publisher Nick Denton announces the sale of neo-feminist site Jezebel to Conde Nast, and Jezebel introduces new rich-brat editors from the midtown Manhattan world its readers loathe. Can't you just feel Big Nick's love for his female readers?
• 5. Larry Brin and Sergey Page call for 30-second YouTube auditions from people who want to settle the planet Mars as part of a Google/Virgin project. Instead of producing slick hoax videos, why don't you guys go build some real rockets?
