Testament is a 1983 disaster drama originally produced as an episode of PBS' American Playhouse but ultimately released theatrically. The film is about the after-effects of a nuclear attack on a small suburb near San Francisco.
Early in the film, Scotty, the youngest child in the central family, watches Sesame Street, before the signal is interrupted by news of the nuclear attack. The two clips are from animated inserts, rather than Muppet clips. Scotty is also seen in multiple scenes wearing a t-shirt with Kermit the Frog on it.
Children's Television Workshop is acknowledged in the end credits for the footage.
