Vegemite is Yummy!! It's got yeast in it, and is very very salty! I love it, but only a little bit, not too much too much is yucky, but its a good spread.
And yeah 'The Evil Vegemite Girls' is a convention tradition we have, i get up and give Vegemite to every actor/ress that comes out to Australia only with 'First Contact Conventions' or 'Culture Shock Events' though! But its fantastic and it just started out as my friends and i giving Rainbow some at our very first convention, then Rainbow ran out of the room calling us evil which is where the name came from since then it's been made a tradition and Scotty who runs First Contact always gets us although it's mostly just me now, but i get up give it to them and make then taste it on stage in front of everyone!
Now when i get up or when the guests are about to get off Stage Scotty will get up and then get me up too and now the whole room cheers when it happens... most of the time anyway!
