I reckon that means No Jokes. All very very serious INDEED. I mean, no silliness in YW is there, hm? Not very much anyway, which is why i have hardly ever bought a copy...
well good luck guys, try not to fight, eat each other, get to pissed for too long, remember there is food other than fry bentos, do not under any circumstances allow TCM to stop near a copper mine, don't wear matching clothes as you will be noticed and expected to be good!!!!!
and most of all enjoy it.
