Well, I thought I'd try this. Say "You haven't lived until ..." and insert an activity that either you've done, been involved with, or has in some way affected you.
Preferrably humorous ones, but anything will do. The only rule is that you have to have been involved with it. So please don't say, "You haven't lived until you've had a lemon signed by Moya" unless you really have had a lemon signed by Moya

Let's start......
You haven't lived until you've had a trader try to sell you a magic carpet in exchange for your shirt in Essaouira, Morocco.
You haven't lived until you've had your favourite Moya song dedicated to you by Moya at a live concert

You haven't lived until you've been stuck in a lift in China.
