The What-If Machine is a machine made out of gold that displays scenarios. These scenarios are given in the form of "what if" questions. The questions only have to make sense in context. At the end of "Twice Told Tales of Interest", the What-If machine (being used as a poker buddy by Bender) self destructed, because of a self-destruct chip Bender used when turning it into a robot thinking it was an Empathy Chip. However, Professor Farnsworth implied that the machine would be fixed in a year. Every time Farnsworth activates the machine, he uses a different button, lever, knob, or switch.
