Wordplay/Dreams for Sale/Chameleon

In the first episode, "Wordplay," Robert Klein plays a salesman. He sells medical equipment and has to become versed in a whole new line. He is trying to memorize the names of the products. The younger sales people have a superior attitude toward him and his older colleagues. Then a strange thing happens. Nouns and verbs begin to have whole new meanings. "Lunch" is replaced by "dinosaur." It starts slowly and pretty soon he is unable to understand anything or communicate in any way. His son is very ill but he can't talk to him. This plays out quite neatly. It is a really original idea. The title "Dreams for Sale" gives the plot away. A beautiful young woman is on a picnic with her husband and daughters. It is utterly idyllic, but soon things begin to repeat themselves, like a tape loop. If you have any imagination, it doesn't take long to figure out what is going on although why this woman is her is up to speculation. The final entry, "Chameleon," is about a trip into space on al Space Shuttle where there is a malfunction in a camera. When it returns to Earth, it begins to absorb people. Despite efforts to isolate the thing, it is able to morph into familiar things, even a nuclear weapon. This is interesting until the writers couldn't come up with a decent conclusion.
