Yeppers. In the league I used to play in we had a "Shark" hat for every foursome.(usually six groups) LOL If a guy missed a three foot putt or seriously botched a hole in the middle of a good round, he was forced to wear the hat until someone else in his group did the same. LOL It made for great conversation and ball busting at the 19th hole. We sometimes had a little betting pool fashioned around who would get the hats or how long they would have to keep them....
