My worst example was the word GIF pronounced like the peanut butter instead of properly as in Graphical. It’s worse because Amanda Montell was writing a linguistics book about the history of language and words.
Recent example was “eschew” which is pronounced Eh-shoo but the narrator said “Eskew” and it confused me so much I had to Google it to make sure I hadn’t been saying it wrong my whole life. What exmaples have you found?
As Sterling Archer once pointed out, the “t” is only silent if your valet is parking your car.
