There was this punter at a bush meeting that backs the rank ousider in a field of 5 runners at 10/1 with a bookie, he puts a $100 on to win.
A little while later he comes back and the bookie who still has it at tens. "Can I have another $200 on that horse?" he asks the bookie.
The bookie takes the bet and then says to the punter, " Look I own that horse and I don't think he can possibly win."
"oh I think he can." says the punter smiling, " I own the other four."
