Skipper was a doll made by Mattel. "Growing Up Skipper" was one version of this doll, with a twist. From wikipedia:
In 1975 Growing Up Skipper was released. The gimmick of the doll, which led to much controversy in the newspapers, was that if Skipper's arm was rotated, the doll would become an inch taller and small breasts would appear on her rubber torso.
If you want to buy one, Growing Up Skipper dolls are available on eBay. Prices range from $8 to $135.
In 1979, when Henri Gugelmann debuted his "rat circus" in downtown Bern, he claimed it was the first of its kind in the world. And maybe it was also the last, because I don't know where one would go today to see performing rats.
His trained rats jumped over ropes, ran through burning rings, and crawled along in a "rat race" while Gugelmann, dressed as a clown, directed the show. That sounds like quality entertainment! [Google News: Victoria Advocate, Aug 9, 1979]
It was back in 1970 that "trucking" became all the rage. The "Youthbeat" column in the Winnipeg Free Press (Oct 19, 1970) attempted to explain what the phenomenon was all about, and how it originated:
"Trucking," the expression for an exaggerated let-it-all-hang-out style of walking, is catching on.
The walk, which emphasizes a long forward step with the body tilted backward and the arms flapping in a Jackie Gleason and-away-we-go style, represent something similar to the Negro spirituals' "we shall overcome."
The walk says: "regardless how much we may be put down, we'll keep on trucking."
The expression originates in a blues song played by Duke Ellington in the 1930s. The lyrics say, "keep on trucking, truck your troubles away."
Kids say trucking around in school halls and outside makes you forget about frustrating classes.
The movement was popularized by the underground press. A cartoon strip which I believe originated in the Los Angeles Free Press and was printed locally about a year or so ago showed a grotesque person "trucking."
The cartoon the writer was referring to is, I believe, this one by R. Crumb:
