You could even start to remember and repeat some of the things that you've heard on Luke's English podcast. After a couple of listens, you'll remember certain phrases, bits of intonation or responses which will be reinforced when you listen again. I don't necessarily expect you to repeat everything I say. The episodes are a bit too long for that. Perhaps you could memorize the lines of a comedy sketch that I present to you and then repeat the lines to yourself or your friends. Or just while you're listening again, you could just repeat it there.
