Contestants try to identify subjects based on definitions given by children.

One of the all-time biggest Goodson-Todman disappointments. The premise seemed to have unlimited possibilities, the kids were clever and adorable, but the game itself was derivative, simplistic and dull.  At the time, Bill referred to this series as one of his personal favorites, although that was probably more for publicity purposes than anything else.  It does have its fans.

Two children seen defining words would later become familiar faces in film and TV. Actress and noted party girl Tara Reid (American Pie, Urban Legend, Josie and the Pussycats, Taradise) and actor Breckin Meyer (Garfield, Robot Chicken) could both be seen defining words on the show.  Arguably the best remembered child player from the series, Sascha Segan, is today a freelance journalist with his own website.

Two pilot episodes, with rules and game play very similar to what eventually aired, were recorded on May 11, 1982.  The pilot called the show a Mark Goodson-Bill Todman production, but the show that aired became the first to be credited just to Mark Goodson Productions.  (Todman had died in 1979.)

All episodes survive and have been seen on GSN: The Network for Games.
