Minister: Oh, yes. I understand you're fond of music. I have arranged a little surprise for you.
Alex: Surprise?
Minister: One that I hope that you will like. As a um... how shall we put it? As a symbol of our new understanding. An understanding between two friends.
Alex: What we were after now was the old surprise visit. That was a real kick and good for laughs and lashings of the old ultraviolent.
Tramp: Can ye spare some cutter, me brothers?
Alex: Excuse me, Mrs. Can you please help? There's been a terrible accident! My friend's in the middle of the road bleeding to death! Can I please use your telephone for an ambulance?
Alex: What you got back home, little sister, to play your fuzzy warbles on? I bet you got little save pitiful, portable picnic players. Come with uncle and hear all proper! Hear angel trumpets and devil trombones. You are invited.
Alex: It had been a wonderful evening and what I needed now to give it the perfect ending was a bit of the old Ludwig van.
Alex: No time for the old in-n-out, love, I've just come to read the meter.
Chosen answer: The droogs didn't like how Alex was leading them, so he attacked them. It's never explained whether the plan was to set him up all along, but given that Din was ready with the bottle to smash him over the head, it seems like an opportunity to be rid of him came up and they took it.
