Ernie (Sesame Street)

Ernie starred in Sesame Street. On the day that the programme and Doctor Who got each other's scripts by mistake, Ernie, now playing a Dalek and holding an eyestalk, shouted "Kill!" as he chased a fleeing Seventh Doctor and Ace along with the rest of the Sesame Street cast. (NOTVALID: Doctor Who? 225)

Behind the scenes
Ernie, as with the rest of the Sesame Street characters, is not named in the story.
