RIP Howard Hessman
This got me to thinking about my favorite WKRP episodes. The next ones after the Thanksgiving episode were the two part show that was the Season 4 start: An Explosive Affair. It mixed a very serious plot with belly-laugh comedy in a way that nothing out of Hollywood has ever matched.
Hesseman carried the comedy part, smashing the phone because he couldn't get through to his bookie to place a bet on "Fever's Break," a longshot that ended up winning. He then becomes paranoid about "The Phone Police," the "secret Ma Bell enforcement branch." He makes it all believable and hysterical at the same time.
