Melbourne Cup 2011

I made a 250% profit this afternoon!  That's through a "Melbourne Cup 2011 Sweep" game I participated in the office this morning - just for fun!  The horse which I bet on came in 3rd place!  How is that for passive income? 

The way this game is played is similar to lucky dip.  Decide on the amount to bet on as there are 2 types of bets - $2 and $5.  I bought one of each.  Then I dipped my hand into each of the envelopes containing all the horses names - these are the real horses names - and if the horse wins, so will I.
