Martin: Oh, you think because of your book smarts, that you can spot a crook just like that, huh?
Frasier: Well if I can't, I'm in the wrong business.
Martin: You want to put your money where your mouth is?
Frasier: Well, what do you mean?
Martin: Well, I've got three people coming over for poker tonight. Two of them are cops, the third one's done time in jail. I'll bet you five bucks you can't tell which one's the ex-con.
Roz: Hey, can I get in on the action?
Frasier: Of course you can.
Roz: Great. Ten bucks on your dad.
Frasier: Oh, you're just itching to give your money away today, aren't you? All right, you're both on. But I think you're underestimating me. What truffles are to pigs, so are these charlatans and pettifoggers to my mental acuity.
