Tell

PICARD :

You have A Tell. 

DATA :

That is impossible, sir. 

PICARD :

Every now and then, 

you dilate your left pupil-

- ostentatiously, I might add-

- in an effort to cheat me 

into thinking that you have a Tell. 

But your true Tell is 

you don't have one. 

When your eyes are neutral, 

that's when I know 

you're bluffing. 

DATA :

Mm. Now that you've 

told me that, Captain, 

I am confused about 

which deception 

to employ.
