look up any word, like cleveland steamer:
A television show from the 70's, that was good in it's first 3 or four seasons, but when they traded Trapper for BJ, and when Alan Alda, who played hawkeye on the show, got behind the camera and directed and wrote. It was about a Mobile Army Surgical Hospital in the korean war. It was also a comedy. Before it was a television show it was a movie directed by Robert Altman, a really good director.

A popular kids' game where by picking 5 boy/girls' names, 5 cars, 5 car colors, 5 jobs, 5 locations, 5 different numbers of kids, and your "favorite number." Under all these lists you put Mansion, Apartment, Shack, House. Count with your "favorite number," marking off an item as you hit that number, until one of each list is left. You should have your husband/wife, # of kids, car, car color, job, location, and type of house you live in. Purely entertainment of course.
