Do you ever put stuff in your friends disc golf bag? I do and I think it's funny. I put rocks in their bags when they're driving to add weight, sometimes as many as three or four a round. You have to be quick so they don't catch you and sneaky so they don't find them right off. I usually try to put them under the discs if they have a roll cage like the Revolution bags do. Or if not, I'll unzip the side pocket real slow and then while they drive, drop the rock in and zip it up real quick. It was funny in the mountains when one of my buddies found rocks once we got back to the condo. He said "no wonder I feel so whooped".
I also put other things in their bags like pacifiers / binkies when they are having a bad round and start whining about their game. One time I found a doggie bag and put it in a golf bag where it could be found, when he asked who did it, I said I thought it might help the next time his game starting to stink.
I also like to throw my bottle caps under the discs in my buddies bags too. Pretty much anything that's relatively small and can be hidden somewhat quickly.
Does anybody else ever pull pranks on your golf buddies like this?
