I have played in a couple scramble events that were fun and goofy...
In one event several holes were played with strange circumstances. This worked great because there were a lot of high handicappers who had a lot more fun than usual.
-375 yard par four. You were only allowed to use a 9-iron for every shot including putting.
-325 yard par four the hole had a toilet seat around it, the kind that is open in the front. You couldn't move the seat so you had to take that into account with your approach shot if you wanted a makeable putt.
-500 yard plus par 5 you were allowed to tee the ball up for every shot.
-par three over a water hazard. If you skipped your ball off the pond and it then comes to rest 'outside the hazard' you can subtract one shot on the hole. (My team had about a 20 yard pitch for an ace on this hole.)
Some nits could be very turned off by an outing like this, but maybe not if you make it clear beforehand that it is all for fun.
