Everything has a natural enemy, and if South Park is to be believed the natural enemy to time travellers is a bunch of cheesed off Rednecks. In one of the best episodes of anything ever, people from the future arrive in South Park looking for work. Its not long before things escalate to typical South Park absurdity. The future people take the majority of jobs in the town and the rednecks decide that the best way to get rid of them is to prevent the future of humanity from happening. How, you ask? By getting into a big man-pile and having sex with each other, obviously. The amount of times "they took our jerrrrrbs" is said in this episode is ridiculous, yet somehow it never gets old and just keeps getting funnier. It's become a meme that's developed a life of its own since the episode aired back in 2004 that's widely used to mock xenophobic attitudes. South Park creators Matt Stone and Trey Parker cleverly use time travel as a plot device to voice their stance on immigration, resulting in one of the funniest episodes they've ever produced.
