Ernie and Bert are two muppets on the long-running PBS children's television show Sesame Street. They appear in numerous skits together, forming a comic duo that is one of the centerpieces of the program. In the tradition of many American movie comic duos, notably Abbott and Costello, the interplay forms between the mischievious innocent (Ernie) and the world-weary partner (Bert ).

A typical skit begins by Ernie coming up with a hare-brained idea and Bert calmly attempting to talk him out of it, and ends with Bert losing his temper and Ernie remaining oblivious to his own bad idea.
