Pugsley and Uncle Fester are blowing up manhole covers but accidentally blow up Sam, a passing motorcyclist, who comes crashing down on their lawn. When Fester tries to fix Sam's motorcycle, Sam stops him and end up getting hurt again. Wednesday quickly rushes to his aid and helps nurse him back to full health. Sam is appreciative of the family's hospitality and notices several artifacts around the house, such as Arturo and Pandora's Box.
