Hi to Doug_Quance

you can tell people about your clique and snub those you don't want in it. You know, kinda like Jr. High!

Hi to youragentsteph

to know why everyone has a dancing banana but me.

you will get your banana soon, steph. Be patient.

doug must have a LOT of karma to have that banana

you get the banana with karma over 25

and several more too... etc....
