Benedict Cumberbatch can’t say ‘penguins’ and it’s adorable

We shouldn't laugh but…

A BBC viewer noticed that Benedict Cumberbatch is having some trouble pronouncing the word 'penguins' on an episode of South Pacific and the clip is going viral. 

The video has been watched over 250,000 times although we're not sure if it has come to the Sherlock actor's attention as of yet.
