Guess Who Owes Lucy $23.50?

S1 E11: A Van Johnson look-alike plays a prank on Lucy and she gives him $23.50 to "fix his car". So when Lucy goes to get it back, Van doesn't recognise her and calls for his security guards to escort her back to her car. But when he realises that a look-alike of his really took the money from her, he feels bad and winds up singing happy birthday to a cow for Cater's Unique Employment Agency.
