Reading the most ridiculous anti-feminist or conservative-with-Christian-or-Tea-Party-bent websites and editing them in my head, writing lab style. The best are the ones that look like they were made in 1997 and are full of lengthy screeds wherein the writer tries as hard as they can to use big words to prove that they're an underground mastermind patiently waiting to bowl over the matriarchal liberal establishment. LOVE IT. Ego stroking fun that doesn't make me feel the last bit guilty.
Update: Reading Kanye's Twitter feed is also included in this category, but that's more awesome and silly than totally depressing.
