Here's some context from the movie Groundhog Day (1993):
Somebody asked me today: “Phil, if you could be anywhere in the world, where would you like to be?” I said to ‘im, “Probably right here... Elko, Nevada.” Our nation’s high at 79 today. In California, they’re gonna have some warm weather tomorrow, gang wars and some very overpriced real estate. Up in the Pacific Northwest, as you can see, they’re gonna have some very, very tall trees.
And also this:
Kenny: That was nice, Phil. “Big trees” [laughs]!
Phil: Stop, Kenny. Look, can you handle the 10 or not?
So, it seems like there's some joke around those very very tall or big trees, which I don't understand. Any help is highly appreciated.
