Show up wearing rhen armor and a worn or rusted spear (any caveman weapon should do) with no leggings or waist
Eat two drinks so your char. becomes drunk, run around for about 20 seconds, post the quest and then immediately ask where you can buy mega potions.
After this, hand everyone in the lobby 10 burnt meats. If you don't have any, find some other useless item. The next best thing to do is to walk up to everyone and do the "Prance" emotion.
Since you're wearing rhen with no legs or waist, this should give them the memory of their father dancing around in his underwear and will disgust them. (unless they're into that type of thing)
Note: This also is a good gag for the skilled players only Ala lobbies. Remember as soon as you post the quest, run up and do it solo. Back out claiming that you forgot your whetstones and try again.
Note2: Does anybody feel like doing the Jho event quest that's going on? I did it the first time and it went rather well.
