Jeopardy! is a popular trivia game show, which has been hosted by Alex Trebek since 1984.

The Sesame Street cast appeared on the show on April 4, 2006, to promote the Season 36 "Healthy Habits for Life" initiative. The first round included a special category, "Sesame Street Eats". When players chose to answer questions in that category, they were shown a short clip of Trebek on the Sesame set, talking with the Muppets about healthy food. Big Bird, Elmo, Rosita and Oscar appeared, as did a dozen Muppet Eggs.
