Monsterpiece Theater is a recurring Sesame Street sketch hosted by Cookie Monster as Alistair Cookie. The sketch parodies the PBS anthology series Masterpiece Theater, originally hosted by Alistair Cooke. In his earliest introductions, the urbane Alistair Cookie held an unlit pipe (which he usually ate by the end). Due to concerns over even the appearance of smoking, the pipe was later dropped, and scenes in earlier skits were re-taped (without the prop). The segment premiered in season 10 and continued to appear on the show through season 32.
