DWTS moment of silence for OK victims

While it was a happy night in the ballroom on Dancing With the Stars, there was a sad undertone. 

Out of one commercial break, everyone took a moment to think about those suffering in Oklahoma. 
Host Tom Bergeron asked the audience not applaud coming back from a break. 
He said, "While we're having a celebration here [in the ballroom], we want you to know our thoughts are with everyone who's been affected by the devastating tornado in Oklahoma City."
At least 51 people including 20 children were killed in the deadly tornadao.
