'Wheel of Fortune' viewers left puzzled during Pat Sajak's 40th anniversary episode

Pat Sajak celebrated 40 years as host of Wheel of Fortune on Tuesday — a milestone noted earlier in the day by daughter Maggie Sajak, who tweeted:

Pat himself sent out a tweet shortly after reminiscing about what was happening four decades ago:

However, fans were left confused following Tuesday night's episode because there was nary a mention of Pat's 40th anniversary during the entire show.

(The shows are typically taped in batches in advance, which might explain the oversight.)

And that wasn't the only puzzling moment Tuesday. During the Bonus Round, when contestant Eric Morgan solved the puzzle, "Whole Wheat Pasta," he started his answer saying "I think, uh…" which viewers at home thought would cost him the win.

In case you missed it, last week fans were upset over a technicality, which cost contestant Charlene Rubush an Audi Q3, after she paused for a few seconds before saying the last word of the phrase. However, after viewers called out for WoF to still give Rubush the car, and campaigned on Twitter, Audi took notice and ultimately gifted Rubush with a Q3 as a consolation prize. And on Tuesday, some thought they were going to have to launch another Twitter campaign, but were surprised Morgan didn't get "dinged."

So maybe Wheel of Fortune didn't say jack about Pat's 40th anniversary, but the episode still ended on a high note as Morgan walked away with a Mazda MX-30 and $59,150 in overall winnings.
