The trio made a total of 190 shorts for Columbia Pictures between 1934 in film 1934 and 1959 in film 1959 . Plot The Stooges are suitors who go on a sit down strike when their prospective father in law James C. Morton refuses to consent the marriages. The strike wins them fame and they receive numerous gifts from fans, including a lot and materials for a house via the United States Housing Authority . The Stooges win the strike and get married, but now they must build their house. Their wives decree that they will have no honeymoon until the Stooges finish the job. Now mad at their nagging wives, they get to work anyway. They eventually finish, but it is badly made. An example of their building skill is a short set of stairs on a wall that Larry says are shelves, and a bathtub he installed on a wall.

In BEAM robotics , a sitter is a type of robot that does not move. Such robots have no self contained means of transportation and are non mobile. Instead of moving, sitters are usually designed to power lights in some sort of pattern. Most sitters are built as decorations rather than serving a practical purpose. As sitters usually have few parts and are not very complicated to build, many newcomers to BEAM robotics start with sitters, as they are a good place to begin learning the basics of the hobby. Genera Beacons Transmit a signal usually a navigational blip for other BEAMbots to use, often as a navigational device. Essentially, these consist of a solar cell, capacitor, LED s , and possibly a solar engine. Beacons are often found within robot games and are used by other robots to use as a base for navigation. Pummers Display a light show or a pattern of sounds. Pummers are often nocturnal robots that store solar energy during the day, then activate during the night. Ornaments A catch all name for sitters which are not beacons or pummers. Many times, these are mostly electronic art .
