Here are some weird things I've noticed recently:

People needlessly repeat the word "is" as in, "The problem is, is that nobody listens." Or "The stupid thing is, is that we've done this before."

The plural of "process" pronounced as if it were a Latin word: "process-ease." "They will have to build confidence in the normal political process-ease."

"Antibiotics" pronounced "anti-bee-otics." Nonsense! It should be consistent with biology, biography, etc.

"Centimeter" (or "Centimetre" if you prefer) pronounced the French way: "Sawntimeter." Doctors and nurses seem fond of this pronunciation. (They're nearly the only ones who use the metric system in the US.) Baloney! It's an English word now, so pronounce it consistently with century, cent, and centennial.
