A slap in the face brought Snoop Doggy Dogg an arrest for alleged marijuana possession at a comedy concert where the rapper gave an impromptu performance.

The rapper (real name: Calvin Broadus) went on stage with fellow rapper Delmar Arnaud at the "I Got the Hook Up" comedy show Friday night at the Universal Amphitheater. While walking backstage, someone slapped him and he alerted a sheriff's deputy who then searched the rapper after smelling marijuana, said sheriff's Lt. Brad Welker.Each rapper was found with less than one ounce of the drug, he said. Both were booked for investigation of misdemeanor marijuana possession and released after receiving a court appearance citation. Police were called in to quell a minor fan disturbance following the arrests.
