Abner and Gladys Kravitz give the Stephenses' newborn baby Tabitha a birthday present: a single share of stock, purchased by Gladys' broker brother. When the stock suddenly rises in value, Darrin wonders if Samantha "arranged" this good fortune via witchcraft. And then, an even more alarming thought strikes him -- what if Tabitha herself caused the stock's unexpected upsurge? Written by Richard Baer, "My Baby, the Tycoon" was first telecast on January 20, 1966. ~ Hal Erickson, Rovi
