Dancing With The Stars Features Joshua Johnson, Who Tap Dances For Penn State Tuition In NYC Subway

Joshua Johnson, who tap dances for tuition money on the NYC subway each weekend, shared a much bigger stage last week when he was featured on "Dancing With The Stars."

Already something of a celebrity after a New York Times feature and a guest spot on "The Ellen DeGeneres Show," Johnson jumped into primetime for a performance in front of what he estimates was 20 million people. The Times reports that he's still about $3,000 short on this year's tuition after about $10,000 in private donations and $35,000 from"Ellen." Catch his appearance with DeGeneres below.
