The Addams Family

Pugsley's late night missile launches cause no less than fourteen sighting calls to the Bureau of Mysterious Space Objects (M.S.O.). The Addamses are about to leave for a combined midnight picnic and snail hunt when they hear an announcement of unknown flying objects in their area. Thinking there might be Martians about, they happily decide to tarry and see while investigators from the M.S.O. converge upon the Addams estate with the same idea. The two parties meet, each deciding that the others are from another world.
