There is some sharpie 'artwork' on one of my buddy's discs that ended up being rather embarrassing the other day.
We were at bird's nest, and mid-round we ran into John Bird (basically the father of colorado disc golf, pdga #387 to give you an idea of how long he has been around) doing some work to the course. We talked to him about the upcoming tournies, and such, then asked if he'd like to take a break from his work and throw a hole. My buddy offers up his bag for him to select a disc, and sure enough he pulls out my buddies sharpie art disc (one that we affectionately refer to as the C*ck Orc, because it is an Orc that someone tagged it with a lovely picture of a big hairy c*ck and balls as a joke) He immediately slams the disc back in the bag and grabs another, with a disturbed look on his face. The next disc he pulls out is a sidewinder, that he parks about 3 ft from the pin. He decided not to play out the hole, and still gives my buddy a weird look every time he sees him...
