I have no idea why people are offended by old sitcoms.

If you want to see Love Thy Neighbour with races reversed watch the U.S sitcom called The Jefferson's, in which I still do from to time. George Jefferson is the black Eddie Booth with more money.

Sanford and Son was wonderfully written, I love to see Fred Sanford have an argument with Albert Steptoe in a cross-over episode.

The Major in Fawlty Towers was a drunken relic and we all had a xenophobic relative in the family.

Don Warrington is a firm supporter of Rising Damp. Rigsby was just mean, gullible man who disliked everyone and everything...apart from Miss Jones. He always fell for Philip pranks and always took his advice on seduction.

Back in the day I remember going out my way to watch Amen, which is about a insulting, mean and a crooked Deacon who likes to know what he could get out of people.
