"But you can bet before we're through You can bet means that you can be so sure of it that you can 'bet' on it. If you 'bet' your friends a dollar that McDonalds is still open because you remember their hours, then you are confident you are right and willing to bet on it. Before we're through means before we are finished here. So this line in summary means, you can be sure that before we finish. --- "This guy's got them scared to death" If you watched the music video, 'this guy' refers to the teacher training them, and all of them are being trained really hard. --- "so pack up, go home, you are through" Pack up everything you have and go home. You are through here means that you are done, finished. It means that he gave up on her, her time here is over. --- "you are the saddest bunch i've ever met" Saddest bunch is similar to 'loser' or 'disappointment'. You are the most disappointing group I have ever met is the meaning of this. --- "Mister, I'll make a man out of you ~" Mister refers to the men that have joined the training to fight. I'll make a man out of you is saying that right now, he doesn't see them as a 'man', which is someone courageous, strong, intelligent, and these types of traits needed for war. I'll make a man out of you means that I will make you into this strong, brave man. Wow that took a lot longer than I thought haha... Hope my explanations make sense!
