Good Question for a Q&A with Cleese and Idle? Any Ideas?

[eeyoremia]

My daughters surprised me with a Ticket including a Backstage 'meet n greet' with John Cleese and Eric Idle as part of their Together Again at Last...For the Very First Time Show. So what do I say? Any ideas? I don't want to say the 'greatest fan' thing ( am not) but Pythonesque humour has got me through some dark days. They hear that a lot I gather.
 Normally, I wouldn't go. I seldom go out now, but I saw Eric Idle 2 years ago and enjoyed his show very much. John Cleese often plays the abusive character and I don't find 'mean' funny anymore. Thoughts anyone???
