Laura (Mary Tyler Moore) warns Rob (Dick Van Dyke) that if he plays an early-morning round of golf, he'll wear himself out and be unable to attend a party that evening for Laura's relatives. Rob pooh-poohs this notion and heads to the links -- coming home hours later with the head cold to end all head colds. Rather than admit that Laura was right, the severely congested and highly feverish Rob puts in an appearance at the party, with catastrophic results.
