Ned's Newt (1997) : 3x26

Ned is showing a health science project to his class that could make or break his passing grade, a film he's made to show where food comes from. The film is extremely strange, however, because of the various roles Newton plays in it: from the Hard-Boiled Chicken, source of the world's hard-boiled eggs, to the Imitation Crab, source of the world's imitation crab meat. Ned's project is initially doomed because of Newton's involvement, but Ned's teacher thinks that it was actually a creative writing project that was due the following week, for which he gets an A+. She wonders where his health science project is, and the final episode ends with Ned saying "I'll be right back," and leaving the classroom.
