The argument could be made that Conker's Bad Fur Day was the last truly great game produced by Rare, and the company really tried to push the boat out when it came to offensive humour. While there are many odd moments in the game - including plenty of references to the popular films of the time - the highlight is the battle with the Great Mighty Poo. Conker is tasked with taking out an enormous living dump, who just so happens to communicate by singing opera at the player. To win you need to pelt him with as much loo roll as you can until he is weak enough to finally be flushed for good.
