Someone doing a really good impersonation of Comedian Steven Wright's trademark dry humor has a Twitter account with some good updates (Twitter: notstevenwright).

Among my favorites:

• In school they told me "practice makes perfect." Then they told me "nobody's perfect." So then I stopped practicing.
• I'm addicted to placebos. I could quit but it wouldn't matter.
• It doesn't matter what temperature the room is -- it's always room temperature.

Apparently such "fake" celebrities are a bit of a tradition (if that word can be used regarding something so new) on Twitter.
