NCIS: Los Angeles, Season 6

[Sam and Callen trailed Turner to his boat. Sam's phone rings]

Sam:
It's a video call from Turner. [he answers the call and the video feed shows him and Callen from behind]

[Callen and Sam turn around and see Turner pointing his phone camera at them.]

Turner:
[laughs] I knew you were trailing me the whole time.

Callen:
Well, you're a slippery SEAL, huh?

Sam:
You could've walked around.

Turner:
Where's the fun in that?

Callen:
[teasing] That toupee act as a flotation device for you?

Turner:
It's not a toupee. Why does everybody always say that? I just have thick hair.
