Hello Traffic Warden, I want a ticket.
The only game we ever play with our local traffic warden is running up behind them, putting our hands over their eyes and saying, "Guess who?" But this seems way more fun and/or likely to end with someone getting a ticket. Traffic wardens aren't exactly known for having terrific senses of humor. A meter maid's reaction to this "game" would probably be to immediately exercise their tiny amount of power in a world where they are universally reviled, and issue a ticket. Even though technically that's not allowed according to the rulebook of the Traffic Warden Game. We're not going to be the ones who tell them that.
