To Russia with Lab Mice is the first segment of episode 63, a parody of the James Bond movies (From Russia with Love in particular) down to the appearance of a Bond imitation.
In it, Pinky and Brain are shipped to Russia as part of a toy testing project, actually part of Brain's plan: he wants to genetically alter caviar with a fish mutating capsule. The caviar will be combined with peanut butter, and once the Joint Council for Economic Development eats it, " it will cause their tongues to stick to roofes of their mouths, rendering them harder to understand than Marlon Brando. In the ensuing confusion I will step into the breach, and take over the world." However, a Russian lab mouse complicates his plans when she takes off with the car containing the capsule forcing Brain to chase after her.
