R. Kelly was in Los Angeles doing a show when he noticed two female fans starting to fight near the stage.  Instead of stopping everything, Robert simply sang for help, and it worked!

In the middle of a 'Trapped In The Closet' verse, Kelly told the crowd to hold up a second and he approached the area of the skirmish.  Once the crowd was quiet and all the attention was focused in that area Kelly said, "Security . . . Se-cur-it-teeeeeey".
