1. Tell him your his father (with noises that sound like Vader's breathing mask)

2. Run up to him and say, "Hey, Luke, we got a sort of..well, how do I put this... ah,yes..problem in the Trash Compacter."

3. Tell him it'll cost 10,000 to get a ship to Alderran.

4.Tell him docking bay 94 and wait until he gets there

5. Ask him who's going to fly a ship if he buys one.

Sorry about only 5, I couldn't really think of any. And it's more like ways to make him complain.
