It's All Downhill From Here - S2-E16
Continuity mistake: While Ralph is invisible in order to eavesdrop on Klein, when Klein makes a crack about Bill being little league, Ralph deliberately knocks the cup in Klein's hand so the coffee spills on his shirt, tie, vest, and jacket in the closeup, but in the next shot Klein is spotless.
