Picture Segment Description
SCENE 1 Olivia notices Oscar the Grouch in the midst of a funk. He explains that he feels rotten because everyone is having fun, but because he doesn't like that sort of thing, he feels different and left out. Olivia shows him it's okay to be different. Oscar is now mad that Olivia ruined his perfectly rotten mood.
Muppets Ernie & BertErnie and Bert are watching TV, but Bert gets bored and decides to play a record. Ernie tells him to turn down the volume, but Bert won't, so Ernie drowns out Bert's music by playing the radio. Bert then retaliates by turning on the blender. With all four things running at once, they blow a fuse, causing a total blackout in their apartment. Bert goes outside to fix the fuse box, while Ernie turns off all the things that were running. When the lights come back on, they decide to play cards instead of fight.
