Fans were left in disbelief as they watched the show, thinking that Sajak had "straight died between takes."
The sudden disappearance of the host, who has been a fixture on the show for over 30 years, fans and the audience scratching their heads.
Ok! Magazine reported that the famed game show host swapped places with Wheel of Fortune announcer Jim Thornton for the bonus round of the episode, however viewers at home were left in the dark about his whereabouts.
The hit series' social media account even poked fun at the mysterious switch, sharing a highlight of the hilarious moment on Twitter.
"Who's this guy and what has he done with Pat?" the caption of the post read, however, some fans didn't seem to catch onto the joke too quickly.
"Where is Pat Sajak for the final puzzle?" expressed one Twitter user, as another added, "where did Pat Sajak go for the last segment of tonight's show?"
"Y'all I done thought Pat Sajak straight died between takes," a third individual morbidly quipped.
It turns out the talk show swap only occurred because one of the contestants was a mega fan of Thornton and had expressed her admiration earlier in the show.
"I love Jim Thornton so much," the contestant Sarah told Sajak earlier in the episode. "And how could someone not? His voice is so soothing and energizing. He's hilarious and just such a good person."
Thank goodness he's okay!
Can you imagine how confusing and horrifying this was for the audience?
