Bewitched (1964)

S2E12 A Strange Little Visitor

Samantha and Darrin take on the task of babysitting a young warlock named Merel. Darrin sets a strict rule for the evening: NO WITCHCRAFT! Merel complies until a burglar unexpectedly breaks in and ties both him and Darrin together. This intruder is after an expensive necklace that Larry entrusted to Darrin for Louise, but Darrin cleverly tricks him into leaving with a fire engine instead. At Darrin's urging, Merel finally uses his magic, scaring the burglar away with his powers.
