I think the hardest I’ve ever laughed at tv comedies has always been British tv. There are two that stand out to me. First is in The It Crowd
They’re in the basement of Reynold industries and Moss accidentally sets a bunch of stuff on fire. He has to call the fire department, but the government changed the emergency phone line to some insanely long numeric jingle. It is hilarious.
Second would be Black Adder. Back in a Medieval ages sniveling Black Adder is trying to impress people by donning the biggest codpiece. The scene where he’s dressed up and there’s a large formal gathering line is uproarious.
