Watch: David Ross busts a move on Week 2 of DWTS

There aren't too many grandpas who can move like Grandpa Rossy.

David Ross continued to impress on the dance floor during his second appearance on "Dancing With The Stars" on Monday. The former big-league catcher and his partner, Lindsay Arnold, ditched the baseball theme from Week 1 and danced a nearly perfect cha-cha set to Young MC's classic "Bust A Move." Ross even lip-synced Young MC's rap perfectly during the dance - which came as no surprise to his old friends with the Chicago Cubs, who've seen the 40-year-old grab the mic a few times.

Ross and Arnold scored 27 out of 40 on their dance, ensuring they'll be busting a few more moves on the show for at least one more week.
