Third Sister Tai marries Dunce Lau and her life has since been between laughter and tears. At the birthday party of Tai's father one year later, Lau's wit suddenly comes back to him. Lau turns the occasion into a stage for displaying his talents and makes fun of his two brothers-in-law who used to despise him.
