Meanwhile across the world we meet the formidable Genghis Khan in Mongolia, and catch up with the crafty Saladin during the Crusades. With of course, our host Rattus to guide the way!

《糟糕历史》是CBBC出品的一档儿童节目，但吸引到了各个年龄段的观众，在IMDB上有高达9.1的评分。该节目用喜剧的视角向观众朋友们展示历史上最囧的一面，涉及到古希腊、古罗马、阿兹台克、印加、世界大战以及英国历史上各王朝等，内容丰富，寓教于乐。几位演员可谓全才，对各种类型的角色的塑造堪称经典，并且能歌善舞。《糟糕历史》中的歌舞桥段，可谓一大看点。总之，一句话形容，就是“外表荒诞无节操，内心高洁学问高”。

Meet an annoying French prankster from the Middle Ages, witness bizarre Aztec food on Historical Masterchef, see what happens when Queen Elizabeth I needs the toilet, and learn how not to impress a woman in Victorian times.
