Horrendously offensive ("taco-flavored-keeses for my Ben"), but funny (if you're watching South Park, you kind of have to take in stride the fact that they're trying to be offensive).  Not my favorite episode, but it still stands out.

One of my favorites. Jennifer Lopez (Fat Butt) is dropped by her record company in favor of a new and younger Jennifer Lopez from South Park who is actually a hand puppet; specifically, Cartman's left hand. The point being that a hand puppet is just as talented as the original J-Lo. Ben Affleck (Pancake Head) falls in love with the new Jennifer so J-Lo "goes Latin" on everybody. I suspect that her personality and temperment may not be too different from the way she was portrayed here.
