You can hear this exchange from the horses' mouths (somebody in France just wrote horse mouths) about 30 seconds into the video below:
Christopher Moltisanti: Russians? They're not all bad.
Paulie Gualtieri: How 'bout the Cuban Missile Crisis? Cocksuckers flew four nuclear missiles into Cuba, pointed them right at us.
Christopher Moltisanti: That was real? I saw that movie, I thought it was bullshit.
