Indulge me here for a moment. . .we're going the long way around on this one, but we are going somewhere.
In the 1998 movie Rounders, Mike McDermott (played by Matt Damon) loses $30,000 playing poker against a Russian man known as Teddy KGB (played by John Malkovich). After a whole lot of drama, McDermott gets an opportunity to redeem himself against Teddy KGB, and he discovers that the Russian has what's known in the poker world as a "tell," or something that tips other players off as to how good a hand he has.
