4x23 - Sanford and Son

Lamont has been in a daze around the house, singing songs and incredibly cheerful to everyone he talks to. Grady and Fred deduce that the boy must be in love. Fred learns that Lamont is on the verge of proposing marriage to one particular girl who works at a dress shop. So he goes down to meet her and is in for a shock, since the girl turns out to be a woman at least ten years older than Lamont.
