YMMV / Yu Gi Oh Anime S 1 E 28 The Night Before

• Hilarious in Hindsight: While snooping around the dueling arena, Tristan, Téa, and Bakura spot a tower outside with a window pointed right at the arena, leading them to believe Pegasus cheats via someone in the tower spying on his opponent's hand. Fast-forward to Battle City, and Joey duels Espa Roba, who turns out to be cheating by doing exactly that.
