Hynkel's speech, which also serves as his introduction. A passionately random speech - it rambles past praising Tomania, condemning democracy, discussing the relationship between Herring and Garbitsch, praising Aryan maidens, condemning the Jews (with a hateful, insulting passion that causes a microphone to pull away from him. This bit is tactfully translated to "His Excellency has just referred to the Jewish people") and seemingly declaring war on all of Europe. All of this interrupted by random fits of coughing, Herring's failed belt-tightening, and a couple of mannerisms borrowed from Hitler himself. See it at http://www.youtube.com/watch?v=Z4UhJpviVYg.
The best part is that it is entirelypseudo-Germanic rubbish including random words such as "sauerkraut", "cheese-und-cracker", "lager beer" and "baloney" and the Black Speech is so difficult to pronounce that Hynkel descends into coughing fits twice.

A second speech, after Herring knocks him down the stairs. Herring, in his fake German, comes up with "der Banana", and they just run with it.

Hynkel's dance with a balloon globe. Never before was Adolf Hitler's megalomania punctured with such graceful comedy.
Hynkel and Napaloni constantly trying to one-up each other.
One that stands above everything is the meeting in Hynkel's office. Garbitsch has set up everything for Napaloni to be intimidated: he'd have to reach Hynkel's desk from the other side of the enormous office, and would be made sit near Hynkel's bust and in such a position where he'd have to look up to him to see his eyes... And then Napaloni barges in from behind Hynkel and salutes him with a manly slap on the back, and continues ruining the whole effort and intimidating Hynkel (and injurying Garbitsch) by being friendly.
The various resistance members all doing their best to avoid being randomly picked for a suicide mission.
