Winston: Happy Bird Day, Dr. Sam.
Sam: Wow, you didn't have to do that.
Schmidt: Did you say, "Bird Day"?
Winston: You heard me. Well, you know, I figured Jess likes you, so I like you, too, man. Welcome to the family.
Sam: H-Hey, look at that. It's a shirt with a whole lot of birds on it.
Winston: That's a bird shirt.
Sam: Bird shirt. What? Why? What-what's the...?
Winston: Ah, you know why.
[flashback to Sam passing by Winston in a bird shirt:]
Sam: Cool shirt, dude.
Winston: [chuckles]
[present:]
Winston: We're bird bros now. And check it out, you can wear it to the party. You know, nothing says, "This dude is dope," like a motherflippin' finch, am I right?
