How do you rename Pokemon on Pokemon FireRed?

Oh, dude, renaming Pokemon in FireRed is like a walk in the park. You just gotta go to the Name Rater in Lavender Town, like, he's the guy who's all about changing names. Just talk to him, select the Pokemon whose name you wanna change, and boom, you can give your Pikachu a new identity. It's like giving your pet a cool new nickname, but way more digital.
