Steptoe and Son S06E07 - The Three Feathers

Having rescued Albert who's got tied up in knots doing yoga, Harold crows over his latest purchase, a Regency commode bought for seven pounds from a woman who wanted rid of it. Then her husband arrives, accusing Harold of taking advantage of his wife's ignorance and offering to buy it back for a hundred and fifty quid - which Harold accepts. After he has gone, an antique dealer arrives and goes into raptures over the commode, offering six hundred. However Harold has to buy it back from the irate spouse at three hundred. Albert points out to him that husband and dealer are two con-men working in tandem and Harold has been well and truly had.
