Nazi: My god! It's you! It's really you! 

Howard: Yes it's me. How did you know I was alive?

Nazi:  I heard rumors. Ghosts, really, hinting that you'd made a life here. But why Washington of all places?

Howard:  Why not? It's the perfect cover. Who'd have thought that I, the notorious son of Hitler, would be marrying the President's daughter.

Nazi:  That's a little bold, don't you think? There will be much public exposure.

Howard:  Yes. Imagine their surprise when they find out I'm also having an affair with her mother, the first lady.

Nazi:  But what if someone recognizes you? You could at least shave the mustache.

Howard:  The mustache is a family heirloom.

Nazi:  But it's a Hitler mustache.

Howard:  It's a "Howard" mustache now. But yes, it'll be a Hitler mustache soon enough.
