There are a few things you should know before Em and Gwyd get back to 'Straya in a few weeks' time. I thought it would be best if you had a bit of preparation for the stories, rumors, and inside jokes they'll be armed with upon their return.
Here's what you need to know:
1. Em and Gwyd are both pregnant with babies made (Mighty-Boosh-like) from barbecued ribs, Indian food, and Dr. Pepper. The appropriate response to this: jealousy.
2. They will definitely try to explain something called an "orc Elvis" or "orc Elvis impersonator." The explanation will probably involve snippets of Elvis tunes, snarling, and discussions of bouffant hairdos. The correct response to this is mildly-amused puzzlement.
3. They have perfected their imitations of American homeschool kids. The correct response to this is to ask them whether or not the Balrog has wings, if Hobbits can be found in Mammoth Cave, or if the economy can survive without the contribution of Wood Nymphs.
4. Speaking of Mammoth Cave, Gwyd has developed a theory about how Mammoth Cave was built. If you ask him about this, be sure he replies in his American homeschool kid voice.
5. The next time you are around them while they're eating, their "Mmm" noises in response to the tastiness of the food will likely turn into an "mmm"-punctuated laugh fest. They might wipe tears. The appropriate reaction to this is awkward silence. I'm sure you can manage it.
Also be sure to ask them about Andrew's reaction to seeing Androdgo, and who carried the food down to the tuberculosis patients in Mammoth Cave. You have a few weeks to prepare yourselves.
