Scooby-Doo, Where Are You!
The gang wanted to lure out the Phantom to be caught in a trap, and wanted to use Scooby-Doo (disguised as a human) as bait. They got Scooby dressed up, but he refused to go any further. So, Fred Jones tried to get Scooby to be brave by telling him to be like Rin Din Din and Laddie, but failed in doing so. However, he succeeded with John Wayne.
