One would think that a man as esteemed and worldly as Benedict Cumberbatch would be a master of linguistics. The subtle differences in language that seperate regions and dialects. He also clearly has been speaking English his entire life, so one might be shocked when they hear the way Sherlock pronounces penguins.
This is not in any way to make fun of the actor. The guy is awesome. It is just one of those things you notice and kind of go hmmmm to yourself. How can such a well-spoken man have trouble with the word penguins? Truth is, we all have our odd ways of pronouncing words. Sometimes, it is because someone who raised us may have said it that way, or in some cases, there may be no reason at all.
I just thought you might find it interesting that Benedict Cumberbatch can't say penguins. Like, really.
Okay, I won't lie. This video is kind of hilarious. I mean, really, who has ever called them penglings?
