Looking for a laugh? Check out Favstar, a site that lists the most popular tweets as selected by Twitter users. Every a tweet is favorited (by clicking on the star icon next to it in your Twitter feed), Favstar indexes the tweet. Tweets favorited by multiple users rank higher based on how many times they were starred.

Visiting the favstar.fm homepage shows the most recent, most favorited tweets, most of which are hilarious. You can view favorited tweets by most popular, those rising in popularity, and newly popular tweets. You can also check how often your own tweets have been added by others as favorites, and search for tweets from your friends or other contacts that have been starred as favorites.
