Pull Someone’s Leg
To pull someone’s leg is to tease or trick them into believing something untrue as a joke. The reviewed histories disagree on how early secure printed evidence should be placed, while a famous supposed 1821 diary example is rejected as a later fake.
It means to jokingly deceive or tease someone. Phrase Finder reports a clear 1883 newspaper example; Grammarphobia reports an earlier 1859 occurrence. Neither source establishes the popular hanging-related origin story.

Further guidance
Chronology Conflict
Phrase Finder’s earliest located genuine example is from 1883, while Grammarphobia reports an 1859 novel occurrence. The engine preserves that source difference rather than declaring an absolute first use.
Meaning
Cambridge labels the idiom informal and defines it as trying to make someone believe something untrue as a joke.
Origin Myth Boundary
A purported much-earlier Gallatin diary use is tied to a diary now regarded as fake, and execution/hanging stories remain unsupported in the reviewed evidence.
