If you are running a game and one of your players ever expresses a desire to run an adventure some time soon:

1. It gives you a chance to relax a bit and play as a player instead of a GM.
2. Even if it goes horribly wrong - especially if it goes horribly wrong - the player will have a better appreciation for how much hard work you put into every session.
3. Accept the offer before they can retract it. Grab it with all possible appendages as quickly as you can!

Leia: Nice.
Chewbacca: Yeah. The school concert is this week. I think they'll be ready.
[SFX]: Door!
Chewbacca: Hi Corey, how's it going?
Luke: Great! I had an idea. I've been thinking about Sally's Robot Utopia, and started writing my own campaign.
Chewbacca: Cool.
Rebel Trooper 1: {in background, quietly} Well, we're ready, but I'm not sure about these new allies.
Rebel Trooper 2: {in background, quietly} It'll be fine. We're survivors, remember.
GM: Great, you can run it after this adventure is finished. What's it about?
Luke: Big guns.
Han: AWESOME.
R2-D2: I'm in.
C-3PO: I hope there's more to it than that.
R2-D2: Yeah. Bigger guns.
Luke: Ooh, good idea. I'll make a note.
