On last night's episode of Family Guy, Stewie, Brian, and neighbor Mort Goldman were all transported back to Nazi Germany via Stewie's homemade time machine. Seeing as how one of them is Jewish, they needed to get out of there quickly, using tactics that reference movies like Top Secret! and Back to the Future. There were a few political jabs in the episode, but none as overt as in the clip above, when the gang has to wear Nazi uniforms to sneak into a laboratory. Stewie notices that his Nazi uniform also includes the added accessory of a McCain/Palin campaign button.

This is pretty amusing, sorry I missed it.
Family Guy's shtick is over-the-top lampooning, like in the "Gloria Ironbox" episode. Some people find this style offensive, I think it's funny for the most part.
