I knew that sounded familiar:
"Meka Leka Hi Meka Hiney Ho" - Magical incantation used by Jambi the Genie (John Paragon) on the Saturday morning children's program PEE WEE'S PLAYHOUSE/CBS/1986-91. Jambi lived in a purple box with two jewel studded doors that sat on a tabletop inside Pee Wee Herman's playhouse. He had blue skin and wore a red turban but all the audience ever saw was his head which floated inside the box bathed in a glow of blue light. Once a jabbering green monster came into the playhouse. "What's he saying Pee Wee?" said Chairy (a talking chair). "I wish I knew" replied Pee Wee. Suddenly the doors of Jambi's jewel covered box opened. "Wish? Did somebody say wish?" Jambi then said "Monster, Monster, I command, Speak so we can understand. Now everyone repeat after me. Meka leka hi, meka hiney ho!" Suddenly, a halo of light filled the room and everyone could understand the monster's language. The deed done, Jambi said "The wish is granted. Long live Jambi." and the doors to his box closed. source
