a friend of mine and his dad went to lunch at Okoboji Grill. His dad is this 60 year old, salt of the earth, farmer, and he ordered an Arnold Palmer with his meal. When the drink comes out, they set down this giant, fruity, umbrellas and pineapple wedges concoction, just reeking of rum. His dad took one look at it, and was like "I ordered an Arnold Palmer." The waitress didn't seem to understand.
After some explaining, it turns out she didn't know what an Arnold Palmer was, and that she had brought him an "Arnold's Park" instead. They all had a good laugh about it, but it occurred to me that that's probably the only restaurant in America where that mixup could have happened.
