In Pokémon Red and Blue, theres a trainer on Route 3 named Youngster Ben. Before battle, Ben will say Hi! I like shorts! They're comfy and easy to wear. For reasons unknown, this struck a chord with the Pokémon community, and Youngster Ben became somewhat of a running gag in future games. In Pokémon Black and White 2, a women in Humilau City will say this dress is comfy and easy to wear, as a direct call back to Youngster Ben. Again, in Pokémon X and Y, a trainer named Youngster Keita can be encountered on Route 5 who will ask the player if she/he wants to know why he likes wearing shorts in the tall grass. After the battle, hell tell you its because they're comfy and easy to wear!
