Synopsis:
A stockholder asks Perry White to give his son, Dexter, a job at the Daily Planet. Dexter turns out to be a practical joker, annoying his co-workers with his antics. One of his jokes causes Lois to suspect Clark is Superman.

Later, Superman plays super-practical jokes on Dexter to convince him to give up his joking ways. The plan works, but Dexter and Clark are kidnapped by a gang of mobsters. One of Dexter’s jokes allows them to escape, and in the process Clark manages to convince Lois that he is not Superman.
