Hitler rants about the Nikon D3x
There are a lot of remixes at YouTube reusing the same scene from Der Untergang. Do a little searching, and you'll see Hitler rant about BMW motorbikes, Windows Vista and other (un)popular products.
Perhaps not in good taste, but I found this one, about Nikon in general, and the new D3x in particular, hilarious. (You probably need to be a bit of a photography nerd to get all the in-jokes).
Here are some more.
