Dee Dee Dee Dee Dog

"Dee Dee Dee Dee Dog" is a Sesame Street song performed by Gina and Oscar in episode 2887. Telly is distraught that everyone has a dog to show the letter D with, until Gina points out that many D words can describe a dog. Oscar then points out the negatives (or positives in his case) of his dog, Preposterous.
