I just put a couple of bucks on a pool I made with my 5 closest friends, for one of the biggest jackpots ever, here in Brazil. We had loads of fun talking about it in the days leading up to the draw. We made fun of each others numbers (one of my friends chose a number that wasn't even part of this particular lotto, another chose the same number twice), and exchanged dozens of emails talking about what we would do and we also made lots of fun of each others choices. Overall we had a great time that we wouldn't have had, especially since now we don't all live in the same city. It was the best 10 bucks I spent this month, so far.
