It's Always Sunny in Philadelphia, Season 5

Charlie:
Says the guy who knows nothing about the law!

Dennis:
I can absolutely keep a hummingbird as a pet, bro. It's no different than having a parrot or a parakeet. It's a bird, bro.

Charlie:
You really can't, and I'm not saying I agree with it. It's just that bird law in this country-it's not governed by reason.

Dennis:
There's no such thing as "bird law".

Charlie:
Yes, there is.

Dennis:
You know what? I'm going to get a hummingbird and I'll show you.

Charlie:
Hummingbirds...hummingbirds are illegal tender!

Dennis:
I'm going to get one.

Charlie:
You cannot.

Dennis:
To spite you, I'm going to get one.

Mac:
Where are we with gulls?

Charlie:
You can keep a gull as a pet, but you don't want to live with a seabird, okay, 'cause the noise level alone on those things...have you ever heard a gull up close? It's going to blast your eardrums out, dude.
