Double It Every Year

Moore predicted chips would double every year. We applied it to attendance, then to cake.

What happened

Attendance doubled from the previous year, exactly as projected, because the committee counted everyone twice. Gordon Moore was counted twice as well and did not object. The buffet doubled next, then the band, then the speeches. By midnight the committee understood that exponential growth has a downside, and its name was the cloakroom.

Elsewhere in 1965

Gordon Moore observes that the number of components on a chip doubles about every year, a trend later called Moore's law.
