Used to be, when I answered my phone at work, I didn't know what to expect. A college frat boy wanting to build the world's largest beer bong. Ashrita Furman, a guy from Brooklyn planning to break the marathon unicycle-riding record for the greater glory of his spiritual leader, Sri Chinmoy. A woman who had toilet-trained her chameleon. I was the associate American editor for the Guinness Book of World Records, and point man in the U.S. for would-be record-breakers.
