Ozzie has tickets to the Riviera Ballet, but Harriet doesn’t want him to go because the actresses will be wearing skimpy bathing suits.
On Halloween night, Ozzie and Thorny make plans to attend a non-costume party as Satan and a Scotsman. Meanwhile Ricky and David attend a Halloween Party at school and the Nelson household is besieged by children demanding candy – or else.
Ozzie quickly regrets advising David against allowing people to take advantage of his good nature.
Ozzie decides to diet so he can fit into a pair of size 38 pants.
David has a rival for the girl they fancy, and his name is Will Thornberry – his next door neighbor.
