“This guy was so large, he had his own climate”

There are many ways to say that a person is big. A man can be “tall as a building” or “have his own zip code.” New York-born comedian and actor Billy Crystal said that, as a kid, he played basketball against someone so large, “he had his own climate.”
 
Crystal used the “he had his own climate” remark since at least the 1990s.
 
“How’s the weather up there?” (said to a tall person) is a similar saying.

Play resumes, and I’m guarding a building in a pair of socks. This is the biggest man I’ve ever seen in my life, he has his own climate. He’s running upcourt, and I’m guarding him and he’s laughing at me.
