I was on a United flight between SAN & ORD a couple of years ago, listening in on Channel 9. Conversation went like this:
En Route Control: United123 cleared direct Gotham City
United123 (a young lady with a soft voice): Errrr - cleared direct to where?
Control: United123 cleared direct Garden City
United123: Ohhh - GARDEN City - Right!
I'm sure he said Gotham City and Ms Pilot did as well. Perhaps it was the Kansas drawl?
