Tuesday marked Pat Sajak's 40th year hosting "Wheel of Fortune" but the episode that aired on his big day left viewers confused for a couple of reasons.

Maggie Sajak announced the longtime host's special day on Twitter, writing, "Happy 40th Wheel-iversary to this guy! On this day in 1981,@patsajak hosted his very first episode of @WheelofFortune…and the rest is history!"

And it was a feat Sajak expressed excitement about himself when listing off his upcoming milestones on the social media platform last week. 

"What a week! Dec 25…Christmas Day. Dec 28…40th anniversary of my first "Wheel" on NBC daytime. Dec 31…32nd wedding anniversary. Jan 1…2022 begins. And it almost has to be better than 2021, doesn’t it? Well, doesn’t it?" he wrote.

So there were a few viewers left perplexed when Tuesday's episode aired without any mention of Sajak's 40 years on the game show. 

"WOW! Not one mention of Pat Sajak's 40 year anniversary on last night's Wheel of Fortune??? This is unacceptable," one fan wrote.

"Wow! No mention of Pat’s 40th year on #WheelofFortune tonight?" another tweet reads.

Another questioned if the show was going to post about it. 

"From what I’ve seen, today marks 40 years since @PatSajak first made his debut on @WheelofFortune… I’m curious if Wheel is going to post anything about it?"

But the lack of mentioning the 75-year-old's achievement wasn't the only thing that left "Wheel of Fortune" viewers confused. According to Yahoo! Entertainment, contestant Eric Morgan seemingly flubbed his answer when solving a puzzle. Before saying the answer "Whole Wheat Pasta" out loud, Morgan allegedly said, "I think, uh…." first, which led many to believe he should have been eliminated due to a technicality.

"Hold up!! Eric added "I think" before solving the final puzzle after Pat told him not to add anything and still won. Wth? Rules are rules, right?" one person reacted online.

Another viewer made a joke that referred to a contestant last week who missed out on a new car for a technicality. "Should we start a Twitter campaign to Mazda to give Eric a new ca—oh…never mind," the tweet reads.

"Surprised #WheelofFortune didn’t ding him for saying "I think uh" before Whole Wheat Pasta," another person said.

Reps for "Wheel of Fortune" did not immediately return Fox News' requests for comment.

'WHEEL OF FORTUNE' SPARKS CONTROVERSY AFTER CONTESTANT LOSES BIG PRIZE OVER A TECHNICALITY

Loyal viewers of the show will remember Charlene Rubush's game that went viral last week when she was not allowed to collect on a brand-new Audi Q3 in the Bonus Round because she paused a bit too long between words in her answer while correctly solving the puzzle. 

Just before the buzzer, Rubush said "Choosing the right… word."

Unfortunately, that brief pause before the last word was more significant than she thought, as host Sajak explained.

"You know, this one's tough because you said all the right words, including the word 'word' but, as you know, it's gotta be more or less continuous. We'll allow for a little pause but not four or five seconds. I'm sorry. You did a good job in getting it, but we can't give you the prize, and it was the Audi."

Fans took to Twitter to complain about the technicality and demand that the contestant receives her Audi for getting the answer correct in the allotted time. And it appeared to work out in Rubush's favor because the car maker confirmed to Fox News that the contestant will be receiving her Audi Q3 after all.

"In the spirit of the holidays, we are thrilled to gift Charlene with an all-new Audi Q3." said Tara Rush, Audi of America Chief Marketing Officer. "It is the season of giving after all and, technicality or not, we are always eager to share a bit of Audi magic and cheer!"
