Approx 10 mins. to the end of the episode "Lucy and John Wayne": During the infamous scene where Lucy wears her purse as a hat after her shock at John Wayne's visit, John, who's decided that Lucy is truly disturbed, states "I think I owe Bill Holden an apology..." Ricky, who is standing next to him, very obviously mouths Mr. Wayne's lines as he says them, just before saying his own line.
