When I first moved from England to Czechia in 2009, I always turned to comedy when I felt a little homesick. The blurb on the cardboard sleeve would often refer to them as "timeless classics," but comedy arguably dates quicker than any other genre, and some old favorites are more timeless than others. I was thinking about this recently when I was writing a piece about "All in the Family" and its British predecessor, "Till Death Do Us Part." Another factor is that some beloved sitcoms date badly because the style of comedy seems archaic after a few decades. Here are five popular shows that haven't aged well.
