OK, so this one technically isn't a punch, but it's close enough. When you finally fight Hitler after countless red herrings - sort of like the whole "Thank you, BJ! But our Hitler is in another castle!" thing - you do technically have the option to whip out your tiny knife and stab him to death. Probably not a smart idea since your little frog-sticker won't hold up well against his chainguns, but if you can time it, you can land a cool finishing blow. "Eva, auf Wiedersehen!"
