History.
I first caught Horrible Histories on TV as I was passing by a few years ago. You know one of the programs that just gets you to sit down and watch? The more of the program I saw, the more it got me hooked. I really liked it and I thought it was one of the funniest programs I'd seen for a long time. Which is strange in itself as I’m not a big fan of comedy shows.My One Big Highlight

Every person watching Horrible Histories will have a particular favourite time period that the show covers in it's unique comedy style. Mine is the World War Sketches, and in particular the Prisoner of War Escape sketch. This clip shows a British officer continuously escaping from the office of the head of the prisoner of the war camp. With the funny reactions from both the British solider and the German General, it perfectly sums up what the show is all about.
Elephant In the Room

Some shows have an excellent first season, and then other seasons pale in comparison. Horrible Histories is exactly like that… just the other way around. The first season isn't terrible, but the first season doesn't have the same amount of polish (especially the songs) as the rest of the series. So bare that in mind. From the second series onwards it remains awesome.
