Find the First Mention of Words or Links on Twitter

Find out who really came up with that over-saturated joke from Twitter with Who Tweeted It First, a site that digs through billions (500 million a day!) of tweets to find the very first mention of a word, phrase, or link. It's a super-simple, intuitive interface that gets the job done and lets us say: Thank you, Becky Haycox, for reading the mental_floss blog way back in March, 2007.
