acting quite bizarrely.In the last month or so, Sajak has put a contestant in a chokehold; claimed he hides in letter-turner Vanna White’s garden; asked a contestant to remove his shirt and tugged on a contestant’s beard.On this past Monday night’s show, he even scolded a contestant who grabbed the envelope in the show’s bonus round: “Don’t ever do it again!”One can’t help but wonder if America’s longest-running game show host has finally had enough — or maybe he was always this strange and grumpy.Getting tired of the wordplay grind would be understandable. He’s been hosting “Wheel” for four decades, since 1981.
