I Love Lucy (1951)

S2E14 Ricky Has Labor Pains

Ricky starts experiencing "sympathetic labor pains" out of jealousy for all the focus being given to Lucy, who is expecting their baby. To help him, she plans a "daddy shower" for him, but Fred transforms it into a "stag party." Not ones to miss out, Lucy and Ethel decide to crash the event, leading to a series of humorous and chaotic moments.
