The most popular guy at my school was 5'1.

New kid- You know that 5'1 guy with the muscles? I'm not intimidated but almost, that guy looks tough.
Guy who's been around school- Yea that's JoJo. The other kids call him GI JoJo, I don't mess with him. He's a good guy to make friends with, he's the most popular guy in school.
