In the 5th season, after Ash got his 8th badge, they get stolen by Team Rocket. Ash was mentioning how he got all his badges. First, he said: 'I got my Glacier Badge from the Violet City Gym...' That's wrong! He got the ZEPHER Badge from that gym. He got the Glacier Badge from the Mahogany Gym... I don't see how these people could've missed that!
