"The World's Greatest Criminal Mind" is a song featured in Disney's The Great Mouse Detective. It is sung by Ratigan and his thugs. This song also includes a special appearance by Bill the Lizard from Alice in Wonderland. This song was included on the VHS, Disney Sing Along Songs: Be Our Guest. The song begins with Ratigan mentioning his earlier crimes, and that his current plan will be even more wicked than before. It then changes to his henchmen singing their admiration of their evil leader before switching to Ratigan lamenting over Basil's constant interference with his plans, before wickedly claiming that not even Basil can stand in his way this time. The henchmen sing their praises again, but the song is interrupted when Bartholomew, a mouse who had made himself extremely drunk throughout the song, loudly calls Ratigan the 'world's greatest rat'. Enraged, Ratigan flings the henchman out his lair and has him devoured by Felicia. Once Bartholomew has been consumed, the henchmen resume their singing (mostly out of fear due to Ratigan giving the implied threat of feeding them to Felicia next if they didn't), and the song ends with them smashing their wine glasses together as Ratigan displays his signature grin.
