JACKSONVILLE, Fla. -- The Jacksonville Sheriff's Office made quite the find when police approached a Riverside home with a search warrant on Tuesday.

JSO 's Gang Unit and Narcotics seized a gun, $14,500 in cash and 17 pounds of marijuana from the home.

JSO's Twitter page added a humorous spin to the big bust by using the #KnockKnock while tweeting out an image of the marijuana findings.
