Cookie Monster is a fictional Muppet character on the children's television show Sesame Street. He is best known for his voracious appetite and his famous eating phrases: "Me want cookie!", "Me eat cookie!", and "Om Nom nom nom" (said through a mouth full of food). He often eats anything and everything, including danishes, donuts, lettuce, apples, bananas, as well as normally inedible objects such as salt and pepper shakers, signs, napkins, pencils, typewriters, telephones, motorcycles, Peabody Awards, trucks, a safe, a VW Beetle, and the Letter of the Day. However, as his name suggests, his preferred food is cookies.
Cookie Monster, Elmo and Big Bird appear in "Francine's Flashback" while Stan watches Sesame Street on the morning of his and Francine's anniversary. he yells at the television that the other Muppets should go as far as to "shoot him (Cookie Monster) in the face" because he doesn't eat the cookies but rather crumbles them with his mouth.
Cookie Monster is mentioned in "An Irish Goodbye" as one of the characters from Sesame Street Francine thinks Hayley is attracted to.
