Psych, Season 7

Gus:
Dude, how're you doing?

Shawn:
Well, they say I might have a mild concussion. And I wasn't able to go pick up Lassie's new dog from the rescue this morning. Oh, and get this, I might have a mild concussion.

Gus:
Do you know who she is?

Shawn:
No, she had no ID when I brought her in.

Gus:
Spoke to Juliet yet?

Shawn:
Huh. She must have her phone turned off, man. But you know, after a good night's sleep, I'm sure she's going to be over this whole breaking up with me thing. I know I am. I was thinking I would go, uh, Costanza on her, just pretend like it never happened.

Gus:
That didn't even work for George Costanza.

Shawn:
C'mon son, you know Georgie doesn't have what I've got.

Gus:
A mild concussion?

Shawn:
Hey, how did you hear about that?

...

Gus:
Dude, you know I'm allergic to gold dust! Remember in grammar school, I had to sit at the gold-dust-free table?!

Shawn:
I don't really remember grammar school, Gus. Ugh, my head hurts for some reason.
