A heartless amusement park owner literally works his ride engineer to death creating new amusements. The engineer is ill but his boss allows him no time off and threatens to fire him if he doesn't keep outdoing his creations. While the owner is on vacation he receives a telegram that the engineer has finally died, which makes him glad, since he won't have to pay him when he gets back. It is a fog-enshrouded evening when the owner returns to his park and decides to test ride the new roller coaster. The owner is not impressed, when suddenly, the engineer's ghost appears in the car seat next to him. The owner says that since he was not afraid of him in life he is not afraid of his ghost, but the ghost says he merely wants to explain his creation to him. Now that the fog has lifted and they are plummeting down the track, the owner screams in terror as he see the track cuts off in mid-air. As the car flies off of the track the ghost says "What's the matter? Didn't I build the world's most frightening roller coaster?"
An alien conqueror is set a task by his king to visit planet Earth and capture three humans and make them slaves. The king feels his general may be a coward since he was given orders to attack Earth but Earth was spared because "there were so many targets I simply overlooked it." The general accepts the task as a simple one and departs for Earth. When he lands he approaches a house where he spies three figures through a window and hits them with stun rays. Bringing them back to the king he attempts to make them cringe by threatening them with death to no avail. The king is outraged and has the general executed. As for Earth, "We shall never invade them, for their will is too resolute." The three figures the general paralyzed with the stun ray were statues, for the alien had never seen a live human before.
A selfish man builds a bomb shelter and stocks it with canned food enough to last for a month. He has the shelter constructed so that when he pushes a button the door will be unable to be opened from either outside or inside for an entire month. The siren goes off and he makes for the shelter followed by his neighbors. He pushes the button and tells them they are not getting in and shuts off his door speaker so he can no longer hear them. They shake their heads and say that just wanted to tell him that the siren was a drill. As he goes to open up a can of food, he realizes he forgot to acquire a can opener.
