Bones, Season 6

Booth:
Bones, at any time did you think that the chupacabra was real?

Brennan:
[laughs] No.

Booth:
Then why did you believe that I saw the Yeti in Nepal?

Brennan:
Because what I said you saw was totally rational.

Booth:
I never saw it. You see, what you did was rationally explain something that never happened.

Brennan:
You never saw the Yeti?

Booth:
Or did I?

Brennan:
No, you didn't! You did? Are you trying to confuse me?

Booth:
I might be!

Brennan:
Okay, what is your point?

Booth:
That things are confusing, okay? Just because you can explain something doesn't mean that it's explainable.

Brennan:
You mean explicable?

Booth:
Sure, like us. We don't make any sense at all.
