Salvadore's was the site of an undercover CIA sting operation that Stan botched in "A Piñata Named Desire".
After fighting over who is the better actor with Roger, Stan mentions his CIA undercover work which Roger dismisses as fantasy. But when Stan heads out for a mission, Roger follows him and discovers it is true. Unfortunately, Stan blows his cover while posing as a waiter and is revealed to only get silent parts because he can't act. Due to Stan's error, fourteen agents are killed. Roger teases him by using the head of one of the agents as a puppet.
