Six Flags Over Texas Serving Up Some Bad Theme Park Food Chalk this one up as one of the strangest park promotions ever. Dallas/Fort Worth’s Star-Telegram reports that park-goers can skip lines at Six Flags Over Texas by eating a roach. Not just any roach, but a 3-inch long Madagascar hissing cockroach. Down one of these crunchy babies and you get a Flash Pass for the rest of the day. I loved walking past the 2-hour waits and packed ride queues at Great Adventure thanks to the Flash Pass. But I don’t think I’m ready to eat something THAT big and nasty for it. Plus, lines are normally shorter later in the operating season. No thanks!
