Conan O'Brien boosts Michigan woman Sarah Killen's Twitter posse

CONWAY TOWNSHIP, Mich. — Last week, Sarah Killen had three Twitter followers.

This week, she has 20,000 — as well as a new iMac computer and offers to help pay for a dress and drinks for her wedding.

The unsuspecting rural Michigan woman has one out-of-work late-night talk show host to thank for her newfound online popularity — Conan O'Brien.

O'Brien decided last week to pick Killen as the only person he would follow on Twitter, turning the 19-year-old's life upside down.
