KARA KENNEDY: Harry and Meghan's twenty excruciating seconds on Family Guy are proof of their descent into the cultural trash can - and America's irritation at their lazy self-entitlement

It's happened faster than many of us perhaps thought. At the start of the year, Harry and Meghan were on everyone's lips. Thanks to the double-barrel onslaught of their Netflix documentary whine-a-thon and Harry's misery memoir Spare, people simply couldn't get enough. Love them or loathe them, they were the conversation. Yet in less than ten months, it seems their inevitable implosion in relevance, their downward spiral towards the cultural trash can, is all but complete. And how sad. A pair whose refreshing presence once said so much, who - as the 21st Century royal couple - offered a bright, modern future of influence (in the truest sense), reduced to the butt of a throwaway gag on a comedy cartoon series way past its prime. Gone are the days of full-episode South Park takedowns. On Sunday, Family Guy - limping on in its 22nd series - featured a twenty-second satire of the pair.
