"Open Sesame" - The magical password spoken by the thief Ali Baba to open the entrance of his secret desert hideaway in "Ali Baba and the Forty Thieves", a tale from The Arabian Nights. The aristocratic English detective Lord Peter Whimsey (starring Ian Carmichael) created by Dorothy L. Sayers who adventures aired on the PBS series MYSTERY used the very same phrase to open the inner door of his home safe. The children's series SESAME STREET/PBS/1969+ was inspired by the very same phrase. The term "Sesame" was chosen with the hopes that the program would "open up" the minds of the children who viewed the series.
