The guys I play with are fun and up for a challenge, so we always play skins and greenies (only paid out for birdies). So, one of our foursome decides to add "barkies". He said he read about it in Daly's book. If a guy hits a tree and still makes par, he gets a dollar from the rest of the threesome. So far, it hasn't happened, but it is funny. Have any of you invented a fun bet like this?
